Tic-Tac-Toe (using a class)

[jay.zyzz]

Tic-Tac-Toe without a class
Write a modular program that allows two players to play a game of tic–tac-toe. Use a two-dimensional char array with 3 rows and 3 columns as the game board. Each element of the array should be initialized with an asterisk(*). The program should display the intial board configuration and then start a loop that does the following.

· Allow player 1 to select a location on the boardfor an X by entering a row and column number. Then redisplay the board with an X replacing * in the chosenlocation.

· If there is no winner yet and the board is not yet full, allow player 2 to select to location on the board for an 0 byentering a row a column number. Then redisplay the board with an O replacing the * in the chosen laction

The loop should continue until a player has won or a tie has occurred.

· Player 1 wins when there are three Xs in a row, a column, or a diagonal on the game board

· Player 2 wins when there are three Os in a row, ac olumn, or a diagonal on the game board.

· A tie occurs when all of the location on the board are full, but there is no winner.

************************************************************************************************

The "class-y" TicTacToe :)
The program should display an appropriate message indicating whowon, or reporting that a tie occurred.

The program needs to use a class TicTacToe. The main function needs to have a loop that drives the action of the game invoking methods on an instance the class TicTacToe.

The TicTacToe class should have a private data member for the game board (a two-dimensional array) and a private data member that keeps track of the current player - among any other private data members the class may require. Alter the state of the game board using public member functions.

I mostly need help with the TicTacToe class program. If someone could get back to me sooner that later, I would appreciate it.

Thanks in advance!

How do you think this should be done when using a class instead of seperate function?

[jay.zyzz]

I know basics but I am going to try what I know. How would you relate the following (let's say it's correct:) in the main? I understand you can call your class/functions and whatnot, but can someone explain how would I go about this problem?

class TicTacToe

{
    public:
        int Pick_Player();
        int Pick_Row();  
        int Pick_Column(); 
        int Check_Board();
        void Choice_of_Row(int); 
        void Choice_of_Column(int); 
        void draw(); 
        bool Check_Move(int,int);
    private:
        int row;
        int column;
        int player;
        int board[3][3];
        char draw[3][3];
};

Well. Thanks for the help, unhelpful peeps :)

Here, I did what I could for those like me out there. I will delete this thread so make a use of it for now.

// library files
#include <iostream>
#include <string>

//standard namespace
using namespace std;

   private:
   char board[3][3]; //two-dimensional arrays

            n++;
