This really shouldn't be that big of a problem... at least I don't think so. I'm having trouble with a validation loop. Here's the code:

CODE

int student = 20;
int num = 0;


while(num <= 0 || num > student+1 && num != 'Q' && num != 'q')
                       {
                              cout << "\nPick the number of the student you wish to edit or (Q)uit: ";
                              cin >> num;
                              cin.get();
                              
                       }




The number verification works fine. However, when you put a letter as the variable, it goes berserk. I've never really needed a verification that stops that from happening, but it'd be nice to finally figure out a way to have that stop.
Thank you,
Benjamin Atkerson

Two good options are

cin.good() (remember to clear the flags if an error is found).
