井字游戏 c++ Agrid 不会重置

Tic Tac Toe c++ Agrid doesn't reset

本文关键字：Agrid 游戏 c++ 更新时间：2023-10-16

我是一个初级程序员。我用 c++ 构建了一个井字游戏。游戏运行正常，直到提示用户重复。这就是问题所在。程序未正确循环。任何帮助将不胜感激。谢谢。

问题是你在赢得游戏后没有清除你的矩阵。矩阵是一个全局变量，因此它是在程序开始时创建的，并且在程序停止之前不会被销毁。循环时，将销毁在循环中创建的所有局部变量，但不会销毁全局变量。您需要手动清除此阵列。像这样的函数：

void clearMatrix()
{
        for(int i = 0; i<10; i++)
                matrix[i] = '0'+i;
}

如果在适当的位置执行矩阵，将清除矩阵。

int main(){
    char repeat;
    do {
    clearMatrix();
    string playername, player1, player2;
    int winner = 0;
    char mark = 0;
    ...
}

如果你在 do-while 循环开始时调用这个 clearMatrix(( 函数，你的矩阵每次都会被重置。

cout << "Player 1 please enter your name: ";
    cin >> player1;
    cout << "Player 2 please enter your name: ";
    cin >> player2;

请注意，您可以使用"cin"而不是"getline"来避免再次键入名称时出错。

还要这样做：

else
            cout << "Its a draw!" << endl;
    }
     clearMatrix();
    cout << "do u wanna repeat?" << endl;
    cin >> repeat;

}

由于您必须清除矩阵，因此按照上述定义在底部调用函数clearMatrix();，同时保留在 do-while 循环中是一种很好的编程习惯。
