Calculator Program

[jaydegabert]

I've been assigned to make a program which can calculate all of the options stated below. I'm receiving an Error message saying "too few arguments to function 'void getOperands(int&, int&)'" and I'm wondering if anyone can help me out with this issue?

getOperands(num1);

This only passes one number when it was initialized with two parameters void getOperands(int& num1, int&num2);
