    Need a little assistance.

    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...
