Restricting a prompt

[ZINX]

I'm new here, hello everybody.

What is the most common way to prompt a user for a choice (eg. to type y/n) so that the program allows only y or n chars to be typed in and disallow any other characters? Also, going back to the prompt if a bad char is typed in.

TIA

Use a loop
eg:

char resp;
while (true)
{
    cout << "Do you want to do something? (y|n) ";
    cin >> resp;
    if (resp=='n') break;
    if (resp=='y') 
    {
        /*do something*/ 
        break;
    }
    cout << "\n\nInvalid response!\n";
}
