Is it possible to modify a string of char in C?

Question

I have been struggling for a few hours with all sorts of C tutorials and books related to pointers but what I really want to know is if it\'s possible to change a char point

Answer 1

You could also use strdup:

   The strdup() function returns a pointer to a new string which is a duplicate of the string  s.
   Memory for the new string is obtained with malloc(3), and can be freed with free(3).

For you example:

char *a = strdup("stack overflow");
