c++ - How to stop my code from reading next character?

Question

I just want to read sign character from user and after this ask whether he/she wants to repeat.

it is something like this:

cout << "Please now enter the sign (+-*/): ";
        cin >> *sign;
        cout <<endl; 

and after some time:

cout << "Do you want to try again? (y - yes, anything else - no): ";
        cin >> *yn;

problem is that if user enters something like "+t" in the first time then 't' is automatically assigned to the second yn character.

So how I can prevent this?

Answer 1

You have two options:

1. Read only one character from std::cin (example)
2. Process only the first character character, i.e., sign[0]
