C ++ CIN只有布尔（0,1） [英] c++ cin only boolean(0,1)

问题描述

我想实现来限制用户仅0或1时，程序要求布尔变量。
I'we试图这样做，但它不工作。它仍然不断地问我打字。

 布尔ELE;
做{
    COUT＆LT;＆LT; 电力币：\\ t的;
    CIN＆GT;＆GT; ELE;
    如果（CIN和放大器;＆安培; ELE == 0安培;＆安培; ELE == 1）破;
    cin.clear（）;
    COUT＆LT;＆LT; Neveljaven VNOS！ ＆LT;＆LT; ENDL;
}而（真）;
 

解决方案

克里斯指出的，你想要做的如果（CIN和放大器;及（ELE == 0 || ELE == 1 ））打破;

I wish to achieve to limit user on only 0 or 1 when program asking for boolean variable. I'we tried to do so, but it doesn't work. It still keep asking me for typing in.

bool ele;
do{ 
    cout << "Elektro:\t"; 
    cin >> ele; 
    if (cin && ele == 0 && ele == 1) break;
    cin.clear();
    cout << "Neveljaven vnos!" << endl;
}while(true);

解决方案

As chris points out, you want to do if (cin && (ele == 0 || ele == 1)) break;
