    Character Array Comparison

    Code:
    char a[10] = "123";
    char b[10] = "234";
    if (a > b) {
         printf("here");
    }
    My question is, what is that comparison doing. Is it comparing the memory address of those two variables? Or what?

    Yes it is comparing the memory address of those two variables. (The value of "a", by itself, is not a member of the array a but the beginning address of the array. Same for "b".)

    You can loop through and compare each character, or you can ... do the same exact thing, disguised as a single function call, using something like strcmp. Assuming of course that you do have strings and not just non-nul-terminated-arrays.

    Hope is the first step on the road to disappointment.
