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

No, you cannot modify it, as the string can be stored in read-only memory. If you want to modify it, you can use an array instead e.g.

char a[] = "This is a string";

Or alternately, you could allocate memory using malloc e.g.

char *a = malloc(100);
strcpy(a, "This is a string");
free(a); // deallocate memory once you've done
