Edit post to include your code in the proper tags ( ) and restate your question in the body of the post itself; in particular, what is the problem you are facing, what errors are there, etc.

Hi, I made my own tic tac toe game if you would like to see, i have included code below.


Here is the .h first

class Board
{
private:
	enum Player {X, O, empty};
	Player board[3][3];
public:
	/** default constructor */
	Board();
	/** @purpose is to place either X or O in a specific row and column
	@pre the board, the position and the player X or O
	@post X or O is placed
	@param char player, int row, int column
	@return void */
	void place(char, int, int);
	/** @purpose is to determine if any player has won
	@pre a board with moves made
	@post true or false is returned
	@param char player
	@return bool */
	bool win(char);
	/** @purpose is to determine stalemate
	@pre a board that is full
	@post stalemate value is true or faluse
	@param none
	@return bool */
	bool stalemate();
	/** @purpose is show board
	@pre a board has been created
	@post board is displayed
	@param none
	@return void */
	void showBoard();
};

here is the implementation file

#include <iostream>
#include "board.h"

using namespace std;

Board::Board()
{
	for(int i = 0; i < 3; i++)
		for(int j = 0; j < 3; j++)
			board[i][j] = empty;

{
	if(board[i][j] == empty)
	{
		if(p == 'X')
			board[i][j] = X;

		if(p == 'O')
			board[i][j] = O;
	}
	else
		cout << endl << "Player " << p << " loses a turn because that spot has already been played!" << endl << endl;

bool Board::win(char x)

			if(board[i][j] == X)
				cout << "	 X	 " << "  ";
		}
		cout << endl;
	}
	cout << endl;
}

ok and here is the driver file

#include <iostream>
#include "board.h"

using namespace std;

int main()
{
Board test;
int r, c;
char p = 'A';

int playerTurnCounter = 1;

test.showBoard();

while((test.win('X') != true) && (test.win('O') != true) && (test.stalemate() != true))
{
	if(playerTurnCounter % 2 == 1)
	{
		p = 'X';
		cout << "Player X's turn!" << endl << endl;
	}
	else
	{
		p = 'O';
		cout << "Player O's turn!" << endl << endl;
	}
	
	cout << "Please enter the row to place for player " << p << " (1-3): " << endl;
	cin >> r;
	cout << "Please enter the column to place for player " << p << " (1-3): " << endl;
	cin >> c;

	test.place(p, r - 1, c - 1);

	test.showBoard();

	playerTurnCounter++;
}

if(test.win('X') == true)
	cout << "Player X wins!" << endl;

if(test.win('O') == true)
	cout << "Player O wins!" << endl;

if(test.stalemate() == true)
	cout << "Game ends in stalemate!" << endl;

return 0;
}

What's the problem with your code ? when i put it into my compiler (visual studio 2008) it works fine for me.. .only problem is i think you have to add +1 to the row and column because right the player has to enter 0 for the first row / column....

[Noparies_CpE]

The problem with my code is when there a winner, the command that i put like
if (winner) cout << "Player O Wins!\nGreat Job!" << endl; doesn`t work..
if there is already a winner it just simply terminates the program..
it doesnt say that Player O wins or Player X wins..it just terminates when there is a winner.. why? is there any problem in my cout?

Works fine, I think. You're just not seeing it.

winner = true;
if (winner) cout << "Player O Wins!\nGreat Job!" << endl;
return winner;
getch();  // THIS IS NEVER RUN

Take the pause out of the function and put it at the end of the program, right before the end of main ( but before the return 0; ). See how that works.
