    C++ Simple division question - i hope

    I'v just started programming in C++ and have to create a simple math game for children. The program randomly generates two numbers and a function is selected i.e + , - etc. Everything is fine except for divide as the answers have to remain whole with no decimal points.

    Has anyone got any ideas on how to generate these numbers?

    Thanx for any help,
    Jason

    integer math leaves the answer as an int after division, as long as you are not dividing by zero. just generate two ints, and divide them.

    I think he wants it so the two numbers have no remainder when you divide. You could try generating a random int, and then multiplying that by some other random int. Then your second number would be a multiple of the other. Hope that makes sense.

    Use instead Integer, float/double.

    Menu

    Thanx for the help on division question - now have that working.

    I'v run into another problem now though. I'm trying to make diffrent difficulty settings via the 'Main menu'. My hope is when you click on the diffrent difficulties like easy hard etc it will randomize up to more higher numbers.

    I know if you were using radio buttons you could put in a command like if (RadioButton1 -> Checked), then what ever you want it to do. Does anyone know what the command is for somthing under the menu bar? (I.e File > Save)

    i'v tryed if (MainButton1 -> Difficulty -> Easy -> Checked) but it doesnt reconise easy.

    Thanx for any help,
    Jason

    learning110, well, what you're talking about? this sounds like you're programming in WinAPI, MFC or whatever, this don't sounds like C++ standard, If I understand you correct.

    If you're trying to ask an Windows programming specific question, ask in the correct board for that - windows programming board. Else if you're trying to make this for *nix, ask in Linux programming board.

    Don't forget to pass info there, without more info, hard to help you.

    for more difficult numbers, just do
    Code:
    rand() % hi + low
    hi, is the highest number you want generated, and low, the lowest generated...
