    So what have you done so far? Where are you stuck?

    It's a large(ish) project, so you'd probably need to do a bit of planning before you start writing the code - at least if you've never done this sort of project before.
    Things you should consider:
    What are your classes?
    How do they connect together?

    This forum, like most others have a rule about homework, and using my words, it states "Do your own homework, but we will help you with details if you need help".

    And of course, it's not urgent to us, even if it's urgent to you. But I can assure you that no one is going to write the whole thing for you - that is an absolute certainty - it's plain too much work.

    Edit: In reference to the other post: Are you actually looking for a C or C++ solution?

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    Are you being paid to do this? I have written something frightfully similar to what you are doing before, actually. I think I spent more time making the GUI look awesome than I spent writing code...

    If you want any of our "expert" help, and you are asking a professional programmer to assist you. Just PM which ever one of us you want most the details as to how much you pay and we'll be plenty obliged to have some code in your possession by the weekend. Otherwise, come on dude, learning comes from experience. Experience comes from practice. Practice comes from doing things on your own and failing sometimes, and succeeding others, but above all, learning from both.

    No, don't do that. This is a help forum, not a job broker. There are sites like rentacoder for that.

    I thought my comment was hostile and sarcastic and would be interpreted as just that, not taken as a legit request for a PM. But I may just be losing my touch

    Didn't feel sarcastic to me. Probably because the last part of the post was honest and good advice.

    No attempt made by the OP , no specific problem mentioned, and therefore I believe this thread has no substance and does not deserve to live.
