What I have so far is:

int main() { int num1, num2; //get two numbers cout << "Please enter two positive integers seperated by a comma: "; cin >> num1 >> num2; while ((num1 < 0) || (num2 < 0)) { cout << "Please enter two positive integers: "; cin >> num1 >> num2; }

I believe this is how you get the user to enter two positive numbers but I don't know how to get Ruby to return the highest value 10 .... 20 or return 0 if not in range.

I would very thankful for any help.

Thank you.
