what are the major differences between C and C++

C was the C++ predecessor. As it's name implies, alot of C remains in C++. Although not actually being more powerful than C, C++ allows the programmer to more easily manage and operate with Objects, using an OOP (Object Oriented Programming) concept.

C++ allows the programmer to create classes, which are somewhat similar to C structures. However, to a class can be assigned methods, functions associated to it, of various prototypes, which can access and operate within the class, somewhat like C functions often operate on a supplied handler pointer.

Although it is possible to implement anything  which C++ could implement in C, C++ aids to standarize a way in which objects are created and managed, whereas the C programmer who implements the same system has alot of liberty on how to actually implement the internals, and style among programmers will vary alot on the design choices made.

In C, some will prefer the handler-type, where a main function initializes a handler, and that handler can be supplied to other functions of the library as an object to operate on/through. Others will even want to have that handler link all the related function pointers within it which then must be called using a convention closer to C++.

To finish this discussion, C++ applications are generally slower at runtime, and are much slower to compile than C programs. The low-level infrastructure for C++ binary execution is also larger. For these reasons C is always commonly used even if C++ has alot of popularity, and will probably continue to be used in projects where size and speed are primary concerns, and portable code still required (assembly would be unsuitable then).

Re Matthew: Well, yes and no. Actually C++ is a separate language in its own right that shares a lot with C.

Type checking for example is much more rigid in C++ than it is in C, so many a program that compiles just fine under a C compiler will result in many warnings and errors under a C++ compiler.

So, while C++ might be seen as "C with classes" by some, it actually is different and targeted at a different audience. C still is the best choice for code that has to be fast while still being reasonably readable and portable, eg. device drivers. C++ on the other hand is mainly used in large projects of millions of lines of code, where C code would become unmaintainable. This is mainly due to the possibility to reuse existing code by exploiting the OOP concepts of polymorphism and inheritance.

I think C is much better than C++ since the syntax is much easier to  write.
Also it's really tiring to compile a C++
program.I really don't understand why they have made C++.I think just knowing C is enough.
Thats all.

The C differ from c++ in these things :
1 the in put /out put in the c ( use printf , for the out and scanf for the input )
2 in c use #include<stidio.h>  , but in the c++ use #include <iostream>
3 in the c CAN NOT use the string type but you can declear  it as an array
4 also there are some deffereant  in function how write the function and how to call the function

these are what i remamber about the deffereance between then  
forgive me if i made any mistake

The main difference between C & C++  is the OOPS technology, C++ is an object oriented programing language, using which one can program using the objects that are been created. C++ have the provision of inheritence, constructors whereas you will not find these in C.
Still C is better then C++ because of its  easy and understable syntax !!!

The main difference between c & c++ is the OOPS(Object Oriented Programming) concept in c++.c++ is an advanced version of c which was made in 1980's in the same lab where c was also made and hence most of the features of c are contained in c++ also,but with a little difference in some of the syntaxes to make c++ more advanced Language.Besides these there is not much difference between them

c++ is extension of c. c++ is super set of c.
the most important feature of C++ is that it is object oriented language.But there are some basic changes made in c++.
for example in c if function don't pas any parameter u have to explicitly write void in brackets.but in c++ you don't need to write.

I think C++ is better than C. Because C++ has OOPs concepts which C doesn't have. C++ is an extention of C. While programming in Java OOPs concepts are important. That's why C++ has been created to overcome C. Many new languages may be created in forecoming years.At that time we will be in position to accept that one. So, we should appreciate new languages in the latest trend. This is what I like.

As children, we knew very few English words, and expressing ourselves was difficult. As our vocabulary grew, our expressiveness grew as well. C++ still provides most of the features of C (and I am hard pressed to remember the ones it does not include), while adding many more features. Greater expressiveness with better flow of thought and ideas is the result.

The main difference between C and C++ is that C isn't object-oriented. Okay---that doesn't actually tell you what you want to know; here are some details:


structs don't copy in C. That is, if a and b are structs then the line a = b; doesn't work. Nor will structs be fed into functions as arguments. The only way to deal with them sensibly is to use pointers to them, or to write functions to copy their elements explicitly. classes (with private members) don't exist in C.

There is no operator and function overloading in C. If a function has a name, then that's it---you can't have another version with the same name that does the same thing with different arguments, as you can in C++. The fact that << and >> (left and right shift) do output and input in C++ is a consequence of the ability of the language to overload those operators. Output and input in C are handled by functions called printf and scanf respectively (these also work in C++ if you want, of course).

In C storage allocation and de-allocation are not handled by new and delete but by a function called malloc. In general, the whole process is a bit more messy in C, but is not too bad once you get the hang of it.

Sigh.  C++ is no slower than C.  If you take a C program and compile it with C++ then the resulting code will run at the same speed, if not faster.  Some of the STL classes are "slower" than their C counterparts if you don't take into account their flexibility and the fact that you don't have to do as much error checking (which C programmers don't seem to care about anyway).  C++ code is often larger due to the massive amount of inlining and templating but this allows the optimizer to work on larger chunks of code.

In the end you can use C++ for anything you can use C for.  If you are not comfortable enough using C++ features, then stick to the C subset.  Just because C++ has high-level features doesn't mean you should use them in every situation.

One reason that that people think C++ is slower is that the original C++ compilers and frontends were pretty crummy.  That is no longer the case. Another reason is that people think of C++ as a high-level language with lots of runtime overhead.  C++ is a low-level, compile-time language.  The major reason that people think C++ is slower is that well-meaning C programmers are simply parroting what they heard from somebody else.  A final reason that C++ is getting a bad rap is that it is being bad-mouthed by C programmers who are just too farm-animal stupid to learn anything more expressive or complex than C.

And yes, I've done plenty of programming in C, BLISS, and machine code.  I designed embedded systems and I do it in C++ because the code is faster and more maintainable.

C is always easy to understand and program than c++.
C is the base and c++ is the extension of C.
In C we are not dealing with complex parts such as linked lists, and also there are no concepts of constructors,overloading and templates are less.
Not only that the syntax is very easy as compared to C++.

The first major difference between C and C++ is that C is a POP(Procedure Oriented Programming) Language whereas C++ is a OOP.

C uses Top Down aproach and focuses on procedures.Data moves as such
Whereas C++ uses bottom up approach and focuses on data(Data hiding,Abstaction)

Dyanimic memory allocation in C by calloc() and malloc() In C++ by new and delete.

C recognizes only first 32 char of string whereas C++ do not pose this limit.

Prototyping is optional in C mandatory in C++

main() may not have a return type in C but return type mandatory in C++

We can assign a void pointer to a non-void pointer in C .No such concept in C++

     void *ptr1="vaibhav";
     char *ptr2="Vai"
     ptr2=ptr1  // valid in C

I've been learning C and getting confused, thinking it was C++!  I was fine all the way - it seems that pretty much all directives work as they would in C; in C++.

Apart from 1 - so far I have discovered that the string type kicks up errors about (string *) not being assignable to the 'void' type.

To get around this, either use an array, or compile your program in C.

1) In C, a void* can be implicitly converted to any pointer type, and free-store allocation is typically done using malloc() which has no way of checking if "enough" memory is requested

2) When converting from C to C++, beware that C++ has more keywords than C:

int class = 2;    /* ok in C. Syntax error in C++ */
int virtual = 3;  /* ok in C. Syntax error in C++ */


3) Calling an undeclared function is poor style in C and illegal in C++. So is passing arguments to a function using a declaration that doesn't list argument types


At last but not least............
4) int main()
{
   int s = sizeof('a');    /* silent difference: 1 in C++ ,sizeof(int) in C */
}

The major difference between c and c++ is that the c++ is an object oriented language. moreover there are so many facilities in c++ which are not in c. obviously if it's the advanced version of c then there must be something more convenient, and that is it's syntax. now see,in c if one has to input something then he/she first has to concentrate at the format specifier, addressof operator ,like scanf("format specifier",&name of the variable); but in c++ one can write only cin>> variable name; without considering it's the string or int or float. Moreover, in c++ there are constructors that automatically initialize the variables , inheritance that will inherit the properties of another class. major issue is CLASSES, that are not available in c.so i am not saying that c is better or c++ is better. it doesn't matter what is better,matters only the usage of anything according to the requirements of the user. if one is comfortable with c then go with c else go with c++. matters only that how much your grip at particular language.

Basically C and C++ are entirely different languages as C is structured,C++ is object oriented language.
Object oriented makes C++ so powerful that enhances our functionality and coding technique.
Even no format specifier needed in C++ as we are using in c e.g %d,%f etc.

c is a middle level language having both features of low level and high level language.its a structured and top down approach programming language.

c++ is a high level language because of its oops implementation.its object oriented programming language.

c has uses structures to bind data and data members but c++  uses Classes.

c has the limited reusability.
c++ extends its reusability with c++.

in C++ data can be represented as live entities with thier name as identifiers and reuse it.

for  standard input and output functions , c uses stdio.h header file and in c++ uses iostream.h.

Function prototyping is optional in c.
Functional prototyping is compulsion in c++.

Data hiding is possible with features of classes and its access specifiers.

the main difference between C and C++ is
that C does not provide protection to the data since by default the data type declaration in C is PUBLIC,where as this is over come by C++ since by default the data type declaration in C++ is PRIVATE,more over C++ has additional properties such as inheritance,data-abstraction,data-encapsulation that's why it is called increment of C.In C++ we make use of templates to genralize the program which is the actual aim of the programmer which is not seen in C.

A person who can exploit OOPS can do wonders with this language.C++ is better than C.
It just lags behind in the compile time.
For long codes C++ is very useful.
Its code is also simple,simpler than C in many cases.C has a simpler code than C++ while doing file systems.

To me not only is C++ a "work smarter, not harder" kind of thing... It at'sa lot of very usefull features including classes, that are helpful even to the novice programmer. For one the cin and cout classes are king over C's input methods.

C++:
cout << "Enter two integers seperated by spaces: ";
cin >> x1 >> x2;

C:
printf("Enter two integers seperated by spaces: ");
scanf("%i %i", &x1, &x2);

The cin can be tested for a bool value in if, while, do-while and for...

int x;
cout << "Enter an integer:";
if (cin >> x) //Tries to assign input to x, fails if input cannot be converted to int.
cout << "That wasn't an int"

C++ on the other hand has Improved enormously, looking at thing like borlands builder 6 it has all the power of robotics and server programming and simple codes.

C language is more complex for big application.C++ is more reliable for big application.C does not supports oops concepts,like we can't create instance of function.But C++ supports oops in well formed.C language coding is cost effecting.But not c++.C language coding could not under stand easily by programmers,if it is more in lines.C++ can under stand easily because every thing in the form of class. c does not have more featurs like polymorphism,inheritence,fuction overoading,etc.But C++ supports all these stuffs.

The main difference between c and c++ is that c is procedural language where as c++ is a object oriented language,c++ differs in OOPS concept from c,
2)--Other than this C++ uses const data,friend function,
3)--c++ structure can contain member function where c structure can not.
4)--The datatype typecast is different in c and c++.e.g(int i=50;float f=(float)i;will convert i int to float)but in c++(int i=50;float f= float (i);).
5)--Other differences are c++ uses its string Datatype where c does not,Boundary checking of array is not in c but in c++ .
6)--Exception handling is done in c++ but not in c.
7)--the input/output operation is done in c++ through cout and cin objects but in c it is done through printf() and scanf() functions..

In C data moves around the system freely,that is there is no security for data,but in c++ data is given more importance.That is done using encapsulation.In c reusability is not possible but in c++ it is done by inheritance,that using the existing features of a class.The other feature is polymorphism which means "one interface multiple methods" which is not available in c.Thus Object Oriented Principles differentiates C++ from C.

1.   C source code file name should be *.c and *.h for implement file and header file.

2.   Variables reference is not supported, so you should not use it in C.

3.   Structure definition is not the same in C++ and C

4.   new and delete operator is not supported in C, you should use malloc and free c function to replace it.

5.   In C, you cannot use template and template class.

6.   From C++ to C, you should exclude every STL, ATL, COM, MFC functions, classes usage. You should write your own code to replace the above functionality.

7.   In C, variable definition lies in the beginning of each function, whereas C++ you can put variable definition wherever you want. Therefore, You should move all variable definition that doesnít lie in the beginning of each function to the beginning.

8.   Class is not supported in C, so you should convert all of class definition in C++ to structures and functions in C. You should also know there have automatic initialization and releasing resource procedure in C++ as constructor and destructor implementation but C has not. The following is a rule to port:

9.   The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type. In C, in default environment setting, sizeof returns the actual size include padding bytes inserted for alignment, whereas C++ doesnít. So you should be very carefully about this situation.

10.   The int type is not a hardware-independent type. You should know, in 16-bit system such as Windows 3.1 environment, sizeof(int) = 2, whereas in 32-bit system such as Windows 2000 & XP, sizeof(int) = 4. Therefore, in C, you should try your best not use int. You can use long (4 Bytes) or short (2 Bytes). This is a critical problem especially for file read and write.

I think c++ is much better than c just because of its object oriented technology. Apart from this c++ supports inheritence, constructors etc  as well which are not supported by c. I feel these are the features which makes C++ more flexible than C. But as C is the initial language which we start with it is the best

C++ is actually an extension of C. It supports OOPs concepts. But all these OOPs concepts can be implemented in C. But its the programmers' responsibility to do this in C. But in C++, the language has built-in capability to support OOPs concepts through classes. Most of the C programs will compile under C++ with/without some warnings. The main advantage of C++ is its maintainability and code reuse and sharing. Again code reusing and sharing can be done in C also but its programmers responsibility. C++ provides facilities through inheritance.
In syntax point of view there are some differences but the syntax of C are valid in C++, of course it may show some warning message. For example, for type conversion,
in C, it should be given as
           (type)variable
but C++ allows function like style as
         type(variable).

The decision to follow C or C++ is upto the programmer and the project which is to be done.

The main difference between c & c++ is the OOPS(Object Oriented Programming) concept in c++.c++ is an advanced version of c which was made in 1980's in the same lab where c was also made and hence most of the features of c are contained in c++ also,but with a little difference in some of the syntaxes to make c++ more advanced Language.Besides these there is not much difference between them

Multiple Inheritance
When the number of base classes Inherited exceeds one then the type of inheritance is known as Multiple Inheritance.
For example in C++, The syntax:
Class D: public A, public B
{
   //code
}


Indicates that D inherits the attributes of the two classes A and B.
Though Multiple Inheritance sounds exciting and very useful it has its own drawbacks, owing to which most OOP languages deny support for this feature. These drawbacks include complexities involved when inheriting from many classes and the difficulty in managing such codes.

In C#, you can specify only one base class for any derived class that you create. C# does not support the inheritance of multiple base classes into a single derived class (i.e. Multiple Inheritance). This differs from C++, in which you can inherit multiple base classes. You can however, create a hierarchy of inheritance in which a derived class becomes a base class of another derived class (i.e., Multilevel Inheritance)

Multilevel Inheritance
You can built hierarchies that contain as many layers of inheritance as you like. As mentioned, it is perfectly acceptable to use a derived class as a base class of another. For example, given three classes called A, B and C, C can be derived from B, which can be derived from A. When this type of situation occurs, each derived class inherits all of the traits found in all of its base classes. In this case, C inherits all aspects of B and A.

C was originally written as a language that was as powerful as assembly but is also portable to other platforms.  There is a common realm of thought that if the PDP-11 had supported "XCHG" instructions, we'd see them as operators in C.

C++ actually evolved from C so those who say "it's another language entirely" are not correct in my opinion.  Original C++ compilers actually generated C code.  Infact, C++ grew from the field as people used C++ in absurd and obscure ways those obscurities actually made it into the language as standards!  No matter how bad the programming methodology was!

This is C++'s fatal flaw, being backwards compatible with C.  The flexiblity of C, essentially a "macro assembler" which "high level constructs".  This doesn't make for good voodoo!  As a high level language it provides a more rigid interface and hard to expand model.  The implicit operations of C++ also make it harder to read, harder to maintain and harder to figure out exactly wtf the scope of something is.

They state that C++ is "OO" however, C can be written as OO as well.  OO is not langauge syntax but rather how the design is constructed.  Just because you use "class" doesn't automatically make your code, "OO" which is another common mistake.  Actually, if you can't understand how to do "OO" in C, you actually shouldn't be writing it in C++ because you definately don't understand "OO"!!!!!

C++ has lots of bad things such as pass by reference, operator overloading, multiple inheritence and copy constructors.  One of the main goals of an "abstraction" is just that.  The user doesn't need to know the details of how it was implemented to use it.  Unfortunately, this is not the case with C++.  You NEED to know how it was implemented in order to use it.  For example, is that implicit copy constructor a shallow or deep copy?  I better know before I pass anything by value!  What the hell does the "+" do?  By the function name, I really have no idea.  Will "-" work on the same data?  I'd rather see a function descriptive NAME rather than a + or - if it's not a real mathematical operation.

Functions and variables are hard to scope.  If you see them in a class you have no idea where they came from.  Are they global? Are they in some nth inherited class?  How about classes that reuse function names of real functions?  Hard to track down what one is being used and you could make mistakes!

What about ease of implementation?  Arrays can be dangerous with polymorphism!  Typecasting back to a base class and indexing will cause corruption of data!!! AND THIS COMPILES FINE!  Now to write a simple array you have to write hundreds of lines of code to do something so simple.  So there's trade offs, to do something simple you need to write tons of code!

C is easier to read and understand.  There are less keywords to make it simpler to optimize and figure out what's going on.  If you consider that people can write bad C code and C++ includes C and more, then obviously C++ is a disaster waiting to happen because you have all the bad habits that can occur in C (from a few simple keywords) to everything new that you can do (a ton of complex, hard to read and understand functionalities and implicit operations).

All in all, if you want high level constructs, use a high level language like Java or C#.  If you want lower level constructs, use C or assembly if need be.  However, never use C++!!!!!!!!!

- C++ has better support for the Object Orientated Paradigm.
- Classes come with private members and methods improving encapsulation.
- Polymorphism, as virtual functions replace the need for passing pointers to functions, and are much more powerful.
- Operator overloading allows for cleaner-looking code. (Who said the syntax for C was much nicer?)
- Templates allow code reuse with different types while retaining type-safety
- Inline functions which are safer than macros.
- Automatic destructors that are called at end of scope allow for easier memory and resource management issues (RAII).
- The standard library useful classes, including string, vector, map etc. Although algorithms are free-functions so that might be considered a "C" concept, their use of templates ensures both type-safety and can allow the compiler to inline, which will actually improve performance (particularly std::sort is often faster than qsort, note all those above who say C is faster).
- Exception handling also makes code look cleaner than having to check return values of all your function calls.

Everything you can do in C which C++ can.
Still C++ Provides most reliable way to do the things by providing OOPs concepts which are not applicable to C. By providing OOps concepts C++ has provided the groupism of functionality. e.g. Encapsulation for object security, polymorphism for poratability, virtual/abstraction for memory management etc. etc. and many more. To implement all these things in C first programmer will have to make his own design pattern and he will have to write so much extra code for making this design pattern itself. But in C++ it is already there. Due to power of OOPs COM/DCOM are on the top of technology.

C was introduced by Dennis Richie and its limitations were
1. Non Object Oriented
2. Complexity
3. Bad Memory Management

On the other hand, C++ was developed by Bjarne Stroustrup and was initially called C with Classes. The four pillars of C++ are
1. Inheritance (eg a child class can inherit features of parent class)
2.Polymorphism (Ability to take many forms)
3.Encapsulation (Binding of methods and data together)
4.Abstraction (Hiding the Implementation from the user)

But still to C leads the C++ in terms of speed, as C++ applications are much slower when they are compiled and also during the run time. There are lots many differences between the two. But for the time being, I will end up here.

A high-level programming language developed by Bjarne Stroustrup at Bell Labs. C++ adds object-oriented features to its predecessor, C. C++ is one of the most popular programming language for graphical applications, such as those that run in Windows and Macintosh environments.

A high-level programming language developed by Dennis Ritchie at Bell Labs in the mid 1970s. Although originally designed as a systems programming language, C has proved to be a powerful and flexible language that can be used for a variety of applications, from business programs to engineering. C is a particularly popular language for personal computer programmers because it is relatively small -- it requires less memory than other languages.

c emphasis is on doing things,but c++ is on data rather then procedure.Top-down approach in c, in c++ its bottom-up approach. The programs are divided into function in c, but in c++ it is called object. in c data is move openly around the system from function to function,but in c++ datas are hiddenand can not accessed by external function.

following are differences:
1. c++ allows oop concept but c doesnot allow oop concept.
2. c++ allows facilities like encapsulation, data hiding, modularity,inheritence which c doesnt allow
3. variable declaration in c should happen before any executable statement but it can be done in c++ anytime.
4. c is aprocedural programing but c++ is object oriented.
5. in c++ it is necessary to function declaration before main function but in c integer and void function doesnt require function decleration before main function
6. c doesnt have iostream header file but c++ has.

Actually C++ is nothing but c with classes.
Hence the first difference is C is not object oriented whereas C++ is object oriented.
Next C cannot handle projects whose size varies around 25000-100000 lines of code.
  but it is possible with C++.
  Next C is more easier than C++  due to its syntax.

C++ is powerful than C not only because of the OOP structure but also because of its other capabilities like STRONG TYPE CHECKING. It enforces you to check the type a variable before you assign it to something else. In that respect you also have Casting operators to use them ... they are provide again for the programmer to think before casting one type to other.

Other difference include defination of function multiple times etc.

Diff. b/w structured, Object Oriented and Visual Programming Languages.

This is a copy n paste of my earlier post that was a reply to a question about the difference between C and C++ and also about Visual C++ or windows programming. Its not exactly a tutorial but some information on C, C++ and Visual C++ that could be valuable for newbies learning these languages. Comments would be appretiated. So here it goes:
C is a Structured programming language. While C++ is an Object-Oriented Language. You can do a lot of stuff in C++ as compared to C.

Structured programming language i.e. C uses modules and functions that perform specific tasks like printing text, performing calculations etc. Functions make it easy for the programmer to divide his programs into a no. of tasks, thus making it easier to program. It uses the concept of divide and conquer. Functions can be either provided by the manufacturer of the compiler (pre-defined functions) or could be made by you (user-defined functions).

You can say that C is a go to less programming as it seldom uses go to statements. Most of the operations in C are done using the following constructs: Sequence, Selection and Repetition. Sequence is a step by step execution of program statements, Selection is the use of conditional execution like the well-known if statement (or functions in C) and Repetition is the repetition of a group of statements like in While statement and For statements.

Object-oriented programming languages (like C++) use the concept of re-usability of software or program components. You donít have to re-invent the wheel. It uses the concept of information hiding, inheritance and polymorphism.

Like in C, C++ mostly uses pre-defined functions. It uses classes to hold data and functions. Data are states of the classes and functions are behaviors of the classes. Functions present in a class manipulate its data. Objects are instances (or implementations) of classes.

Classes communicate with one another so they provide that data to other classes that is necessary and hide the rest of the info. It is much like driving a car without knowing its internal working.

Inheritance allows one class to inherit some properties like data and functions from other classes. The class that inherits is called sub-class and its parent class (from which other classes inherit) is called the super class.

Polymorphism is one interface but many implementations. You can do a lot of stuff by giving one command. I think thatís all you need to know about polymorphism at this moment.

For programming in Windows you will have to use Visual C++. However you will need to learn C++ to use VC++. In MS-DOS and LINUX based programming the C++ program calls the operating system to get the user input and in Windows based programming the OS i.e. Windows issues messages whenever a user inputs something e.g. mouse clicks and button press etc for all of these special messages are sent to the C++ program. The messages sent by Windows are mapped in the C++ programs to perform a specific task using a the data received from the OS.

I hope that this helps. If you have any doubts then donít hesitate to ask.

everything is C.. a method called bootstraping is used to make anything from C.. (Something like.. C++ compiler is made from C.. and C compiler!!.. is made from.. maybe ASM.. its like I invent wheel.. and you make a bycycle.. :). )

Anyway.. C++ is an C extension.. But with many new programing constructs. And much much more robust.. and easier than C.. if you really know the benifits of C++..

Look for Design Patterns.. C is a very primitive language.. you can do anything and every thing in it.. Completly an UNMANAGED code.

With more and more emphasis being put on cross-platform environments, we are able to re-evaluate how a language fits into the big picture. Depending on the granularity, control, speed, or efficiency you need to write a program you would use a different language. Larger data management programs may be written entirely in Java. However, that same project with a few graphic demonstrations may requires pieces of the program be written in a language with closer access to memory and processes, like C++ or C. More "advanced" languages may come along to logically map code flow, at a cost of performance. As our logical data structures get more complex, we are able to grow as programmers and thinkers. One of the main concepts of OOP is encapsulation--to take complex functions and thinking of them as a single unit. The more complex our single logical units become, the more advanced our code can become. So, take it in stride and stick to what you want. Just remember, you always have the option of writing assembly.

These are the differences between c and c++
->C++ allows the programmer to create classes, which are somewhat similar to C structures. However, to a class can be assigned methods, functions associated to it, of various prototypes, which can access and operate within the class, somewhat like C functions often operate on a supplied handler pointer.
->C still is the best choice for code that has to be fast while still being reasonably readable and portable, eg. device drivers.
->C++ on the other hand is mainly used in large projects of millions of lines of code, where C code would become unmaintainable.This is mainly due to the possibility to reuse existing code by exploiting the OOP concepts of polymorphism and inheritance.
->C++ applications are generally slower at runtime, and are much slower to compile than C programs. The low-level infrastructure for C++ binary execution is also larger. For these reasons C is always commonly used even if C++ has a lot of popularity, and will probably continue to be used in projects where size and speed are primary concerns, and portable code still required

basically c++ is an object oriented language and c is an procedural based language. since c++ is extended version of c so it must have lots of difference between them.
C is completely based on function methodology while  c++ based on function and oops concept. it is not a pure object oriented language.
C++ has features that gives more security over c language.
We can say c is a low level language and c++ is a high level language.
c is weakly type checking language(like array definition) but c++ is strong(strictly) type checking language.
regarding key-terms c++ has many more features over c.

Although the languages share common syntax they are very different in nature. C is a procedural language. When approaching a programming challenge the general method of solution is to break the task into successively smaller subtasks. This is known as top-down design. C++ is an object-oriented language. To solve a problem with C++ the first step is to design classes that are abstractions of physical objects. These classes contain both the state of the object, its members, and the capabilities of the object, its methods. After the classes are designed, a program is written that uses these classes to solve the task at hand.

concept of C++ is rated much higher than C.  Main difference between C and C++ is that C is a procedure oriented language while C++ is object oriented one. that means using the concept class in c++ object oriented features like data hiding, encapsulation, data abstraction, inheritance, polymorphism is implemented.

Polymorphism means same name having different forms,  In C++, we can write more than one function with same name but it should differ in arguments.

Inheritance means the ability to extend the class features without disturbing the base class.

Data hiding means using the access modifier private, we can hide the data members from external world

Encapsulation means wrapping up to data members and member functions into a single unit, that is also implemented by class.  data members means the variable that we are declaring inside a class and member functions means the functions declared inside the class.

Data abstraction means we use the member functions with out knowing the complexity of the function, ie user use it as simple as it is.

thats all guys enjoy reading, enjoy writing and enjoy  browsing

Although it is possible to implement anything  which C++ could implement in C, C++ aids to standarize a way in which objects are created and managed, whereas the C programmer who implements the same system has alot of liberty on how to actually implement the internals, and style among programmers will vary alot on the design choices made.

In C, some will prefer the handler-type, where a main function initializes a handler, and that handler can be supplied to other functions of the library as an object to operate on/through. Others will even want to have that handler link all the related function pointers within it which then must be called using a convention closer to C++.

To finish this discussion, C++ applications are generally slower at runtime, and are much slower to compile than C programs. The low-level infrastructure for C++ binary execution is also larger. For these reasons C is always commonly used even if C++ has alot of popularity, and will probably continue to be used in projects where size and speed are primary concerns, and portable code still required (assembly would be unsuitable then).

C++ is the improved version of C. C++'s new features, such as simplified memory allocation/deallocation, help programmers make C++ programs more readable, more maintainable and less bug-prone than comparable C programs. Stronger Type Checking - the use of classes, inheritance & automatic type
conversions mostly eliminates the need for the abominable void* of C.

The main difference between C and C++ is the OOPS concept,especially the concept of inheritence.In C functions are implemented through data structures and algorithm,whereas c++ uses classes and objects.Also,the concept of abstraction is applied in the functional level in C.Whereas abstraction is applied on object level in C++.The data being operated upon and the algorithm are separable in C.In C++, the data and algorithm cannot be separated!!!

1. c is procedure oriented language while  
   c++ is being of follow rules of oops so its a object oriented programming language but not pure object oriented programming language because it doesn't follow all features of oops like 'persistence' this feature not follow by c++.

A few major C++ features not available in C:
- Classes
- Templates
- Exception handling
- Function overloading
- Operator overloading
- Namespaces
- Standard library for templated collections, strings, common algorithms,
etc.

And a few minor ones:
- bool type
- Reference types
- Somewhat stricter type checking than C
- new/delete instead of malloc()/free()
- New syntax for declaring struct types

C++ is obviously more complex than C, but many of the added features are
designed to make life easier (string handling is a good example). Some
programmers like to use C++ as "a better C". Others think that the OO
features in C++ makes it more suitable for larger projects than C. Still
others prefer the relative simplicity and sparsity of C.

To explain the difference by enumerating features just gives part of the
picture. Another way to say it is that C++ is a multi-paradigm language,
with support for procedural, object-oriented and generic programming, while
C supports procedural programming only (it's possible to write OO code with
C, but it's not pretty). If this is a good or a bad thing is obviously a
matter of opinion. IMHO the standard library alone makes C++ worth the extra
learning effort.

C is a procedural language which laid emphasis on functions whereas C++ is object orientedwhich laid emphasis on data . In C data is global ie. any function can transform data from one form to another. In C++ data is hidden ie the data and functions that operate on that data are bind together in a object. C follows top down approach whereas C++ follows bottom up approach.
The Concepts of Inheritance and constructors
are also present in C++.

C++ is a direct descendant of C that retains almost all of C as a subset. C++ provides stronger type checking than C and directly supports a wider range of programming styles than C. C++ is "a better C" in the sense that it supports the styles of programming done using C with better type checking and more notational support (without loss of efficiency). In the same sense, ANSI C is a better C than K&R C. In addition, C++ supports data abstraction, object-oriented programming, and generic programming (see The C++ Programming Language (3rd Edition)"; Appendix B discussing compatibility issues is available for downloading).

I have never seen a program that could be expressed better in C than in C++ (and I don't think such a program could exist - every construct in C has an obvious C++ equivalent). However, there still exist a few environments where the support for C++ is so weak that there is an advantage to using C instead

None forces you to use everything a programming language has to offer (unless your pride easily gets hurt when other C++ programmers see your "C++" code).

However, even if you program in C, you can reap the benefits of C++ other then OOP: i.e. templates and inlined functions were some things "I would kill for" in C. You can think of them as of very, very advanced preprocessor features.

If none is pushing you to learn everything at once (i.e. for exam or job interview), keep on programming as you were and eventually it will become clear to you when and where some language features would fit just right and help you ease your tasks. Whenever you get that feeling "Oh, no, now I have to type all this once again" or "Now I'll have to copy and paste this several pages, and then manually edit certain lines", or any other situation where you have the feeling you *almost* already did something previously, but now has to do it again a little differently, you should look up in a C++ book if there is a solution for your problem. In most cases there is. C++ was created by very experienced C programmer who probably had same problems you may have at present time.

enjoy programming!

The difference between C and C++ are enormous.
first C is modular programing language where C++ is OOPs
there are three paradigm of OOPs
1) Encapsulation
2) Inheritence
3) polymorphism

The concept of class and object comes into picture when talking of any OOPs(C++) language. The classes binds the data members and member funtion together. And everyting in OOPs is considered to be a real world entity. This makes C++ more close to real world.

now lets talk of diffences appart from above said:
1) C doesnot support error handling
2) No generic Classes
3) C is just a subset of C++ to have backword compatiblity.
4) No nested function definitions (although some compilers provide them, for example, GCC)
5) In C++ Support for one-line comments beginning with //
6) Run time Polymorphism
7) Operator and function Overloading
8) Storage operators new and delete.
9) Inlining added in C++
10) Stream objects for I/O.
11) There are no reference types ( i.e. types with & ) in C.
Pointers are generally used instead of references.


The C++ programming language was derived from C and is Bjarne Stroustrup's answer to adding object-oriented functionality with C-like syntax. C++ adds greater typing strength, scoping and other tools useful in object-oriented programming and permits generic programming via templates.

Languages was originally implemented as preprocessors -- source code was translated into C, and then compiled with a C compiler.
But all appart this C code is more efficient as there is no ruun time polymorphism.

form the language of c some more concepts are add into c++


There are a few semantic differences between C and C++ in the way they interpret certain language constructs. These differences may not result in a compiler diagnostic, so it is important to pay attention to them when porting code from C to C++ and vice versa. For example, in C, the size of an enumeration equals the sizeof of an int, whereas in C++, the size of an enumeration doesn't have to be an int. Also, in C, the result of applying the operator sizeof to a character constant, for example, sizeof('c'); equals sizeof(int). In C++, on the other hand, the expression sizeof('c'); returns sizeof(char).

Also every valid C program (as said by C++ Creator) is a valid C++ program. But a C program with variable names such as new, private, protected, public can't be a valid C++ program.
Anything that can be done by C++ is doable in C and to a certain limit vice versa is true. I could not imagine a operating system kernel in C++. UNIX kernel's are in C but not in C++, since C code provides lean and mean code than C++.
On speed I would really say on the algorithm that a code follows. Such as a quicksort algorithm in C++ can beat a insertionsort that is written in C, but then quicksort implemented in C & C++ may yeild same result almost every time you run the program. I would say both the beasts C & C++ are required such as two eyes for a human being are so important to him/her. Use the tool C/C++ as per the needs & for the operating platform you deal with.

in the case c we can't create dynamic objects

and also we can't inherit the structures .

2) re-usability of the code by using templates in the case of c++ .

3) data hiding is not possible in the case c  , but in case of c++ it is possible.

Put simply it appears C++ can do everything that C can do, but it does some things, that C wasn't originally designed to do, more easily.

I have a basic knowledge of C, and, like others, I find the syntax of C++ strange at first sight, but once you're over that, it reads very much the same as C.

It's fairly common knowledge that you don't need to know one to learn the other, some think it helps to learn C before C++... of course it would help to know how the logic works etc, but if you want to learn C++ then you might as well just go straight into that. They should both be as easy as one another to learn, but if you learn one you'll have to get your head around the new syntax to program in the other.

As for which is better, it seems they both have their pros and cons, but at the end of the day, they do the same things in a different style to each other. The 'style' of C++, as already stated by others, "allows the programmer to more easily manage and operate with Objects".

I'm choosing to learn C++ simply because it's supposed to be easier to program when using objects. But I would not say that C++ is better than C or vice versa.

I write this because I have been looking for someone to tell me should I learn C or should I learn C++.

The main difference between C & C++  is the OOPS technology, C++ is an object oriented programing language, using which one can program using the objects that are been created. C++ have the provision of inheritence,polymorphismm,operator overloading,data hiding,reusablity of code, constructors whereas you will not find these in C.
Still C is better then C++ because of its  easy and understable syntax !!!

C++ is an extension of ANSI C. As such C++ provides for the following features that are not part of the C language. (1)Stream objects for I/O. (2) Inlining and overloading of functions. (3) Default values for function arguments. (4)Storage operators new and delete. (5) Support for classes. (6)
Support for abstract data types by providing for information hiding and the definition of a public interface. (7)Support for object-oriented programming through inheritance and dynamic binding.

Forgot to answer the actual question: which direction you should go?  It really depends on what you intend to do with it.  

If you are going to stick to engineering type programs and programming controllers, stay with C.  Lots of C experts out there if you have any questions.

If you are going into developing GUIs or stuff for Mobile Phones, try C++.  You can develop GUIs in C too but it is easier in C++ in that each control is an object.  Some people use C++ like a lazy variant of C i.e. they use // for comments and make declarations all over the place: not just at the top of the routine.  All C++ compilers will compile C.  Lots of C++ experts in cyberspace if you get stuck.

If you wish to be tied to Microsoft and .net, torture yourself and have to change compilers every year or so, you could try C#.  Most people are still learning C#: it is only about 4 years old.  I'd wait another two years before trying C# - it is like Visual Basic when it started.  A new compiler is released every year with new features and it is just too much for carbon based lifeforms.

there r quite a few no. of differences in between these two languages.

in C everythin is conceptualised in the form of functions, the focus is more on procedure rather than data. the data is always global so dere is always chances of it being mishandeled. no code reusability as all the functions are dependent on each odr so even to write a similar prgrm wid slight changes but of the same concept u hav to write another piece of code which isnt the case in c++.
type checkin den in C++ is more stringent in C++. c++ is more clse to real wrld programmin as evrythin is coceptualised in the form of objects...this accounts for code reusability also...

C++ is an extension of C language. This means that you can not only use the new features introduced with C++ but can also use the power and efficiency of C language. C and C++ are no more language for writing compilers and other languages, these general purpose languages are used worldwide in every field.
Here is a list of differences between c and c++.
The main difference between C and C++ is that C++ is object oriented while C is function or procedure oriented. Object oriented programming paradigm is focused on writing programs that are more readable and maintainable. It also helps the reuse of code by packaging a group of similar objects or using the concept of component programming model.  It helps thinking in a logical way by using the concept of real world concepts of objects, inheritance and polymorphism. It should be noted that there are also some drawbacks of such features. For example using polymorphism in a program can slow down the performance of that program.
On the other hand, functional and procedural programming focus primarily on the actions and events, and the programming model focuses on the logical assertions that trigger execution of program code.

C is a general programming language.  Small compiler, lots of free compilers.  Quite easy to learn once you get the hang of the syntax.  It is available on almost every platform you can think of.  Note that there are 3 main variants of C: K&R, C89 and C99.  Most compilers are C89.

C++ is an Object Oriented variant of C.  If you are going the C++ route, don't learn C first: you'll get into a lot of bad habits.  However, it is a big language with lots of new concepts.  If you are intending to write GUIs, this is probably the way to go.  It is not available on as many platforms as C.  There is a standard library of algorithms STL which does all the standard stuff like linked lists, vectors etc.  There are lots of free compilers about.
