int GetNonNegativeInteger () { int input; cin >> input; while (input < 0) { // display error message. // ask for input again } return input; }

Change the red code to this:

cout << "Negative number not allowed." << endl;
cin >> input;

cout << "Negative number not allowed." << endl; cin >> input;

Which is what you have in your code, just slightly different each time, which is correct. If you are not going to use a function, doing it the way you did it is correct and is equivalent. When you learn functions, you'll probably do it the way I did it since you are doing the same thing five times. You did it right.
