strcpy using pointers

Question

I\'m trying to write strcpy on my own using pointers and I get an error during runtime.

void str_cpy(char **destination, const char *source) {
//    char *s1         


        

Answer 1

For simplicity's sake, this can be done in one line in a function.

void mystrcpy(char *dest, const char *src) {
  while (*dest++ = *src++);
}

This being said, you do need to allocate memory for dest beforehand using malloc or just simply by having a character array like char dest[256].
