    help in tic tac toe with looping only

    i was required to build two player Tic Tac Toe Game in Dos mode.
    but there is some error in my code..can any body help me pls.. i very depressed abt my assignment i am workin on it 4 a week and i dont know wahts wrong with it. can some one kindly coorrect m code.. thanks a ton

    Requirements:

    You cannot use arrays in this assignment.
    There will be nine boxes on the screen numbered from 1 to 9. Game should prompt the player number who has the next turn and ask that player to enter a number between 1 and 9. If the user enters a number of a box which is already occupied, the game will give an error and ask the user to re-enter his move.
    Both players will use the keyboard to input their move, one by one.
    Computer should tell whether the game ended successfully either in draw or Success of any player.
    Game can be ended at any time if any player enters zero. But computer should prompt the message either you want to quit or resume the game.
    There will be only one undo move. undo will be done if any player enters -1. Then his last move should be removed from the board and he should be prompted to enter the move again.
    The game should ask the names of both players at the start.
    Move of player 1 should be indicated on the board by a O and move of player 2 should be indicated by X
    Your should write separate function to check a move for validity, another function to check if a player has won or if the game is draw, another function to input player names, and any other functions that you can make.
    Your main function should have a loop that should take user moves and perform the functions accordingly. "

    Code:
    string 'box1'=" ",'box2'=" ",'box3'=" ",'box4'=" ",'box5'=" ",'box6'=" ",'box7'=" ",'box8'=" ",'box9'=" ";
    The variable names should not have single quotes around them.


    Code:
    	if (con==6)
    void win();
    	 while ((win==1||win==2||win==0)!){
    What exactly does the call void win() aim to achieve? It appears to be a function prototype, but you cannot have these within other functions.

    There are too many errors to quote them all, and your program structure also needs working on. Grab some paper and hash out a structure, then start coding.

    To undo a move, you must know what the last move was. So, you should have a variable that contains the index of the last square that had an item placed in it. When the user specifies UNDO, just erase the item from that square.

    I guess the first lesson for you is that you should not write 350 lines of code before pressing compile.

    Work in small units you can manage - say 10 lines max. If you get an error after adding 10 new lines, you've got a pretty good idea that the new problem is in the new 10 lines.
    Same with testing, make sure they work before adding more stuff.
    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.
