But you're referring to strcmp(), which is just one string comparison function.
You could write your own that returned a boolean value very easily:
bool strings_match(const char* str1, const char* str2) {
return strcmp(str1, str2) == 0;
}
... or actuall compare each character in the string and return whatever you
like.
But the whole reason that strcmp() returns an integer (and not a boolean) is
because it tells the caller (you) which string is "greater" (for sorting
purposes), which can be very handy indeed (e.g. if < 0, then str1 is less than
str2). So it does more than just tell if you 2 strings match, it tells you how
the 2 strings compare with eachother.
