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;
