C++的调试错误真的很令人沮丧

所以我正试图在C++中制作一个非常基本的TicTacToe，虽然我没有明显的语法错误，但我有很多调试错误："Cobra.exe中0x0100142D处的未处理异常：0xC0000005:读取位置0xCCCCCC359的访问冲突"

我觉得这是一个明显的错误，我只是没有处理，但它；It’我肯定开始紧张了。我会标记访问错误的位置……现在它；s在我的将赢方法中，但我觉得肯定不止一个。。

在我的标题中，我使用了一个私有的char**板和一个私有int播放器。

            cout << "Player " << newGame.getPlayer() << " choose a row and column.";
            cin >> rowChosen >> colChosen;
            newGame.setGame(rowChosen,colChosen);
        }while(newGame.setGame(rowChosen,colChosen)==false);

    char checkWin();
    void displayBoard();
    int returnWinner();
