意外接受用户输入c ++类

Question

刚开始使用C ++中的类，我在请求用户输入时遇到奇怪的事情。

条件语在getUserWantToPlay()成员函数中接受两个结果：＆＃39; y＆＃39;或者＆＃39; n＆＃39;。否则，它将输出请求正确响应的消息。我正处于构建的早期阶段，我只是对这个成员函数进行了一些测试，我注意到当我输入＆＃34; yes＆＃34;或＆＃34;不＆＃34;就好像我输入了＆＃39; y＆＃39;或者＆＃39; n＆＃39;。为什么会这样？

int main()
{

    //Assumes no play unless user decides they want to play and initializes game variable to TicTacToe class
    bool play = false;
    TicTacToe game;

    play = game.getUserWantToPlay();

    while(play == true)
    {


        std::cout << "Playing the game" << std::endl;
        break;

    }

    return(0);
}
