    Smile String in range.

    My order is defined as 'A < a < B < b ...< Z < z'.
    I have to find if a given string is in range or not.
    Ex. If my range is AaA - BaB, AA or AaaB is inthe range, but not CbAA.

    I am looking for any pointers, ideas, suggestions to help me start.

    Does converting everything to uppercase (just for comparisons) work?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper
