Are Pointer to String and Pointer to char both synonymous?
char *s;
is a pointer to char.
but since a string is a char array, and array name automatically decays to a pointer in assignment, so i could use the same definition for a string
Confirm if i m right?
Yes for your last question.
Remember that a string has to have a '\0' char to denote the end of the string. If you pass a pointer to a single char to a function expecting a pointer to a string, unless that one char is a '\0', you're possibly playing with undefined behavior.
Alternatively one might think that a pointer to string in C is a pointer to a char array / a pointer to a pointer to a char.
I might be wrong.
Quoted more than 1000 times (I hope).Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

str is a pointer to a char array.
But str is a pointer to a char (not a pointer to a pointer to a char). str is of type char * .(and here str points to H).
