如何用C++开发井字棋游戏 二维数组和胜负判断逻辑

char board[3][3] = {
    {' ', ' ', ' '},
    {' ', ' ', ' '},
    {' ', ' ', ' '}
};

char checkWin(char board[3][3]) {
    // 检查行
    for (int i = 0; i < 3; i++) {
        if (board[i][0] == board[i][1] && board[i][1] == board[i][2])
            return board[i][0];
    }

    // 检查列
    for (int j = 0; j < 3; j++) {
        if (board[0][j] == board[1][j] && board[1][j] == board[2][j])
            return board[0][j];
    }

    // 检查对角线
    if (board[0][0] == board[1][1] && board[1][1] == board[2][2])
        return board[0][0];
    if (board[0][2] == board[1][1] && board[1][1] == board[2][0])
        return board[0][2];

    return ' '; // 没有胜者
}

char currentPlayer = 'X';
bool gameEnded = false;

while (!gameEnded) {
    printBoard(board); // 打印当前棋盘
    makeMove(board, currentPlayer); // 当前玩家下棋
    char winner = checkWin(board);

    if (winner != ' ') {
        printBoard(board);
        cout << "玩家 " << winner << " 获胜！" << endl;
        gameEnded = true;
    } else if (isBoardFull(board)) {
        printBoard(board);
        cout << "平局！" << endl;
        gameEnded = true;
    } else {
        currentPlayer = (currentPlayer == 'X') ? 'O' : 'X'; // 切换玩家
    }
}
