C ++使用用户输入重复查询

Question

我想要做的是问一个简单的问题，使用 1 或 2 作为输入的是或否。如果他们说 1 或 2，那么它将继续使用代码。但是如果他们说数字（7）或字符（'q'），那么问题将再次重复。我还没有弄清楚如何重复问题和输入。 这是我目前所拥有的：

#include "stdafx.h"
#include <iostream>
using namespace std;

int main()
{
int answer = 0;

do
{
cout << "Are you Bald? Yes(1) or No(2)?" << endl;
cin >> answer; cout << endl;

    if (answer == 1)
    {
        cout << "You Are Bald." << endl;
    }

    else  if (answer == 2)
    {
        cout << "You are not bald." << endl;
    }

    else { cout << "Please Input proper answer" << endl << endl; 
} while (answer < 1, answer > 2);
system("pause");
return 0;

Answer 1

试试这个：

    #include "stdafx.h"
    #include <iostream>
    using namespace std;

    int main()
    {
    int answer = 0;
    while(1)
    {
        cout << "Are you Bald? Yes(1) or No(2)?" << endl;
        cin >> answer; cout << endl;

        if (answer == 1)
        {
            cout << "You Are Bald." << endl;
            break;
        }

        else  if (answer == 2)
        {
            cout << "You are not bald." << endl;
            break;
        }

        else 
        { 
           cout << "Please Input proper answer" << endl << endl; 
        }

    }
    return 0;
}
