    How may I get a random character from A to F?

    char foo = 'A' + rand() % ('F'-'A');

    Think ya need to add 1 to that:
    char foo = 'A' + rand() % (1 + 'F' - 'A');
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    Amazing, thanks. Never thought about doing random stuff like that. In fact, you can place whatever you want in that string and it'll work.
