问题描述
当程序要求布尔变量时，我希望将用户限制在 0 或 1 上.我试图这样做，但它不起作用.它仍然一直要求我输入.
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: ";
cin >> ele;
if (cin && ele == 0 && ele == 1) break;
cin.clear();
cout << "Neveljaven vnos!" << endl;
}while(true);
推荐答案
正如 chris 指出的，你想做 if (cin && (ele == 0 || ele == 1)) break;
As chris points out, you want to do if (cin && (ele == 0 || ele == 1)) break;
