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

char *a = "stack overflow";
char *b = "new string, it's real";
int d = strlen(a);

b = malloc(d * sizeof(char));
b = strcpy(b,a);
printf("%s %s\n", a, b);
