Create a C++ console application that allows two players to participate in a tic-tac-toe game. The program will be responsible for deciding who wins the game.

The program should include the following class, properties and methods:

Code:

    class TicTacToe{
             private:
                    char theBoard [3][3];
             public:
                    TicTacToe(void);
                    void playOneGame(void);
                    void switchPlayer(char &);
                    void showBoard(void);
                    void postMove(int, int, char);
                    char determineWinner(void);
    };

    int main (void){
            //test the class by playing one game
            TicTacToe Game1;
            Game1.playOneGame();
    }

    void TicTacToe::playOneGame(void){
          //start a game and play until someone wins or a draw occurs...
          const int MaxMoves = 9;
          char currentPlayer = 'O';
          int row = 0;
          int clmn = 0;
          char theWinner = ' ';
          int nmbrOfMoves = 0; //keep track of the number of moves max is 9

          do {
                switchPlayer(currentPlayer); //change player from x to o or vice versa                
                showBoard();           

                cout << "\n\nPlayer " << currentPlayer << endl; //get the players move 
                cout << "enter your row: ";
                cin >> row;
                cout << "enter your column: ";
                cin >> clmn; 

                postMove(row, clmn, currentPlayer); //post the move to the board      
                theWinner = determineWinner();  //see if anyone won the game
                nmbrOfMoves++;  //keep track of the number of moves

          } while ((theWinner == 'D') && (nmbrOfMoves < MaxMoves));

           showBoard(); //show the ending board

           if (theWinner != 'D')  //declare a winner
                cout << "\n\nThe Winner is player " << theWinner;
           else
                cout << "\n\nThe Game was a Draw";
    }

    TicTacToe::TicTacToe(void){
              //intialize the array contents
    }

    void TicTacToe::switchPlayer(char &currentPlayer){
             //switches the current player
    }

    void TicTacToe::showBoard(){
            //displays the board
    }

    void TicTacToe::postMove(int row, int col, char value){
           //gets the users move and posts it to the board
    }

    char TicTacToe::determineWinner(void){
          //analyzes the board to see if there is a winner
          //returns a X, O indicating the winner
          //if the game is a draw then D is returned

          //check the rows
          for (int i = 0; i < 3; i++){
                if (theBoard[i][0] == theBoard[i][1]
                     && theBoard[i][1] == theBoard[i][2]
                     && theBoard[i][0] != ' '){
                     return theBoard[i][0];
                }
          }

          //check the clmns
          for (int i = 0; i < 3; i++){
                 if (theBoard[0][i] == theBoard[1][i]
                       && theBoard[1][i] == theBoard[2][i]
                       && theBoard[0][i] != ' '){
                       return theBoard[0][i];
                 }
           }

           //check the diagnals
           if (theBoard[0][0] == theBoard[1][1]
                  && theBoard[1][1] == theBoard[2][2]
                  && theBoard[0][0] != ' ') {
                  return theBoard[0][0];
           }

           if (theBoard[2][0] == theBoard[1][1]
                   && theBoard[1][1] == theBoard[0][2]
                   && theBoard[2][0] != ' ') {
                   return theBoard[2][0];
           }

           return 'D';
    }

The output of the program should be similar to this:
[ ] [ ] [ ]
[ ] [O] [ ]
[ ] [ ] [X]

Player X:
Enter row of move (1, 2, 3): 3
Enter column of move (1, 2, 3): 1

This is what I have so far...

}

I suggest you stop programming while drunk
