The preprocessor replaces the line #include <stdio.h> with the system header file of that name, which declares the printf() function amongst other things. More precisely, the entire text of the file 'stdio.h' replaces the #include directive. This can also be written using double quotes, e.g. #include "stdio.h". The angle brackets were originally used to indicate 'system' include files, and double quotes user-written include files, and it is good practice to retain this distinction. C compilers and programming environments all have a facility which allows the programmer to define where include files can be found. This can be introduced through a command line flag, which can be parameterized using a makefile, so that a different set of include files can be swapped in for different operating systems, for instance.

It includes the suite of standard io functions, meaning the standard input and output functions, into your program. Hence the name, "stdio" - standard i/o :)
