Question

I have two char* references and I am trying to figure out which one is less. The code I have is:

bool stringComparison::lessThan(char *s1, char* s2) {
  int result = strcmp(*s1,*s2);
  return result < 0;
};

the result is not producing less than 0 ever. How do I need to change the “int result” line to make this work?

thanks

Answer 1

strcmp is used to compare strings; *s1 and *s2 are characters. You should be calling strcmp with s1 and s2 (no stars).

EDIT:

Here is the reference for strcmp
