        int e = 5*5*5;
        int f = 6*6*6;

    The last part with int a-j......
    Is there a better way of doing this, like possibly putting into a loop and showing output from maybe a single piece of information? I hope im asking this question right.....

    --- Update ---

    Or really is there a better way of adding them up.... to reduce coding

    Yes, there is a better way. Try your loop idea and see what happens.

    Why do most of your answers to questions 1 - 5 have incorrect capitalization?

    capitalization doesn't really matter... just answering the question.

    ummm.... as far as the loop goes,

    I'm not very keen on the loop idea but I'll do a little more reading and find out.
