c++ - 无法结束 while 循环 (C++)

Question

我似乎无法结束这个 while 循环，我已经尝试了所有我知道的方法，但它仍然无法正常工作。即使我已经将其更改为“false”，变量“contGame”也会一直更改为“true”。你们能帮帮我吗!请注意，这在一个类中。这是我的代码:

while (contGame == true)
    {
        if (turn == 1)
        {
            cout << Board._player1Name <<"'s turn!!\n";
            X = getMoveX();
            Y = getMoveY();

            Board.Board[X][Y] = player1Sign;
            Board.printBoard();
            turn = turn + 1;
            Board.checkGame(contGame, player1Sign, player2Sign);
            if (checkGame(contGame, player1Sign, player2Sign) == false)
            {
                bool contGame = false;
                cout << contGame << endl;
            }
        } 
        cout << contGame << endl;
        if(turn == 2)
        {
            cout << Board._player2Name <<"'s turn!!\n";
            X = getMoveX();
            Y = getMoveY();

            Board.Board[X][Y] = player2Sign;
            Board.printBoard();
            turn = turn - 1;
            Board.checkGame(contGame, player1Sign, player2Sign);
            if (checkGame(contGame, player1Sign, player2Sign) == false)
            {
                int contGame = 1;
                cout << contGame << endl;
            }
        }
    }  

这是 checkGame:

bool contGameA = true;
for (int k = 0; k < 3; k++)
    {

        if (Board[k][0] == Board[k][1] && Board[k][1] == Board[k][2] && Board[k][2] == player1Sign)
        {
            cout << "\\\\" << _player1Name <<" wins!////\n";
            contGameA = false;
        }
        else if (Board[k][0] == Board[k][1] && Board[k][1] == Board[k][2] && Board[k][2] == player2Sign)
        {
            cout << "\\\\" << _player2Name << " wins!////\n";
            contGameA = false;
        }
    }

for (int r = 0; r < 3; r++)
    {
        if (Board[0][r] == Board[1][r] && Board[1][r] == Board[2][r] && Board[2][r] == player1Sign)
        {
            cout << "\\\\" << _player1Name << " wins!////\n";
            contGameA = false;
        }
        else if (Board[0][r] == Board[1][r] && Board[1][r] == Board[2][r] && Board[2][r] == player2Sign)
        {
            cout << "\\\\" << _player2Name << " wins!////\n";
            contGameA = false;
        }   
    }

if (Board[0][0] == Board[1][1] && Board[1][1] == Board[2][2] && Board[2][2] == player1Sign)
    {
        cout << "\\\\" << _player1Name << " wins!////\n";
        contGameA = false;
    } else if (Board[0][0] == Board[1][1] && Board[1][1] == Board[2][2] && Board[2][2] == player2Sign)
    {
        cout << "\\\\" << _player2Name << " wins!////\n";
        contGameA = false;
    }

if (Board[0][2] == Board[1][1] && Board[1][1] == Board[2][0] && Board[2][0] == player1Sign)
    {
        cout << "\\\\" << _player1Name << " wins!////\n";
        contGameA = false;
    } else if (Board[0][2] == Board[1][1] && Board[1][1] == Board[2][0] && Board[2][0] == player2Sign)
    {
        cout << "\\\\" << _player2Name << " wins!////\n";
        contGameA = false;
    }
return contGameA;

Answer 1

您实际上是在 if 语句的嵌套范围内创建了 contGame 变量，这隐藏了在外部范围内声明的 contGame 变量。因此，您永远不会更改外部 contGame 变量

例如

if (checkGame(contGame, player1Sign, player2Sign) == false)
{
    // bool contGame = false; should be:
    contGame = false;
    cout << contGame << endl;
}

和

if (checkGame(contGame, player1Sign, player2Sign) == false)
{
    // int contGame = 1; should be
    contGame = true;
    cout << contGame << endl;
}
