Question

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);

Answer 1

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