Yes.
p will point to certain memory location that will contain the address of the string . which certainly you don't require.

when u say char*p p is the character pointer.
it will hold the address of a memory loction where a character can be stored.

we can say char*p ="hello"
in this case we are declaring p as pointer and storing the characters of the string in continuous locations.mentioning the string itself will give the address of the string.


if u say *p it becomes derefrencing a pointer.when u use a * with a pointer it will give u the value pointed by that pointer.so *p ="hello",will show an error.

char *p;
*p="Hello";
It produce logical error because *p points the single value of the p. Here we can assign a single value only
like
    *p='h';
    *p=65;
    //etc.

we cannot assign address of the string.
