    Why not write some? I doubt you'll find too many people who are willing to just hand you all their code, especially since it sounds like a sort of homework thing.

    I have the codes written in Java. Since Java is similar to C++, perhaps you could convert them to C++. When you are done, please post the C++ codes into this forum.

    There are two files - TicTacToeServer.java and TicTacToeClient.java

    1) TicTacToeServer.java

    Code:
    import java.awt.*;
    import java.awt.event.*;
    import java.net.*;
    import java.io.*;
    import javax.swing.*;
    
    public class TicTacToeServer extends JFrame{
        private byte board[];
        private JTextArea outputArea;
        private Player players[];
        private ServerSocket server;
        private int currentPlayer;
        
        public TicTacToeServer()
        {
            super("Tic-Tac-Toce Server");
            board = new byte[9];
            players = new Player[2];
            currentPlayer = 0;
            
            try{
                server = new ServerSocket(5000, 2);
            }
            
            catch(IOException ioException){
                ioException.printStackTrace();
                System.exit(1);

    I have the codes written in Java. Since Java is similar to C++, perhaps you could convert them to C++. When you are done, please post the C++ codes into this forum.
    Are you for real ?

    It's a huge job 'converting' a java program with gui into a c++ program with gui, not sure if it's even possible.

    well, I think that was his point....to show the original poster that doing his own code would be less work....

    No, actually it was a mistake on my part. I thought of helping but I made a mistake by writing it in Java. By the time I finished writing, I realized that it wasn't Java forum but C forum.

    javacvb: I swear that looks like the code from Deitel's "Java How to Program" book. For that matter, the internals look similar. There are a few differences, like the port number, etc. but they are small.

    Yes, it is. I was joking. Sorry. Actually, I tried the code under NetBeans IDE 3.5.1 then I visited this forum & found that someone is looking for Tic Tac Toe. So I guess, it might give him some ideas.

    If the networking part doesn't confuse him first.

    Problem is it's confusing to read for me without Eclipse's nice syntax highlighting (I'm getting to used to that).

    Well since the OP hasn't returned (or more likely, found their homework somewhere else), and this is now off-topic, I think we're done
    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.
