C++ C++；而声明获胜'；不要在第一次之后就停止重复

我试图为一个编程类编写代码，出于某种原因，我发现只有当您对问题的第一个回答是“n”时，它才会重复。否则，无论您输入什么，它都会继续重复

while (again == 'y')
{
cout << endl << endl;

    break;

    default:
    cout << "That answer is invalid. Please input only an 'I' or an 'O.'";
 }

 cout << endl << endl;

 cout << "Would you like to run the program again? (y/n)\n";
 cin >> again;

while（同样=='y'）
{
cout请再次删除循环中
的定义。

它可以防止
在更新时在
的条件下再次计算
。
这不应该是主要问题，但我认为
中的分号是if（board='N'）；
应该被删除。你试过调试你的代码吗？你发现了什么？请发布一个。这不是完整的代码，所以很难说。但是，你应该以尽可能高的警告级别编译，并注意所有的警告。变量
中应该有一些东西。你提到过吗循环。您的第一个语句是循环。块在第2行打开，但从不关闭。。
