Compare strings |
To compare two strings, not just to see if they are "equal" ("abcd"="abcd")
but tell their alphabetical order:
string a, b;
a = "abcd";
b = "bbcd";
Can all the ways below to do such comparison?
1. a > b
2. a.compare(b))
3. strcmp(a, b)
4. max(a, b)
Which one you prefer and why?
Thanks!

This is good. What could be simpler?
2. a.compare(b))
Reminds me of a Fortran II IF statement, and that isn't a glowing
recommendation. :)
3. strcmp(a, b)
I don't like this one because it won't work. However if you ammend it to
strcmp(a.c_str(), b.c_str())
I still don't like it. Using char * as a string type is a leftover from C.
4. max(a, b)
This is good too, if that's what you mean. It means something different than
#1 of course.
Which one you prefer and why?
Thanks!
