Cross_and_zeroes

Welcome to Cross_and_zeroes, a simple yet classic console game of Tic-Tac-Toe implemented in C++. This project serves as a great example of basic game logic and console-based user interaction.

Features

  • Classic 3X3 Grid: Play the traditional Tic-Tac-Toe game on a 3x3 board.
  • Two-Player Mode: Alternate turns between two players, X and O.
  • Automatic Win Check: The game automatically checks for a win condition or a draw after each move.
  • Random First Player: Randomly select which player goes first at the beginning of each game.
  • Game Statistics: Track the number of wins for each player and the number of draws.

How to Play

  1. Start the Game: Run the executable to start the game.
  2. Input Coordinates: Players take turns inputting the coordinate of the cell where they want to place their mark (X or O).
  3. Win or Draw: The game will declare a winner if three of the same marks align horizontally, vertically, or diagonally. If all cells are filled without a winner, the game ends in a draw.
  4. Play Again: After each game, you have the option to play again, with the win statistics being updated accordingly.

Code Overview

The main logic of the game is encapsulated within the Game class:

  • Attributes:

    • Board[3][3]: The game board.
    • X: The current player’s mark (either 'X' or 'O').
    • Result: Indicates the result of the game (1 for X win, 2 for O win, 0 for draw).

  • Methods:

    • ShowBoard(): Displays the current state of the game board.
    • GetCoord(): Prompts the current player to input a coordinate for their move.
    • EmptySquare(char): Checks if the selected cell is empty.
    • Check(): Checks if there's a winning condition on the board.
    • swapX(): Switches the current player.
    • NewGame(): Initializes a new game session.

Code Snippet

void Game::ShowBoard() {
    system("CLS");
    for (int i = 0; i<3; i++) {
        for (int j = 0; j<3; j++) {
            cout << "|" << Board[i][j] << "|";
        }
        cout << "\n";
    }
    Check();
}

void Game::GetCoord() {
    char ch = '1';
    cout << "Input COORD(" << X << "): ";
    cin >> ch;

    while (!EmptySquare(ch)) {
        cout << "Input COORD(" << X << "): ";
        cin >> ch;
    }

    Board[0][ch - '0' - 1] = X;
    swapX();
    ShowBoard();
}

bool Game::EmptySquare(char x) {
    return (Board[0][x - '0' - 1] == x);
}
