This compiles with no problem, but my calcCost function returns jibberish. I’ve tried many different combinations and I know it’s something simple. If I change my calcCost function to void and cout totalCost, it works fine, But I need the return value for another class (Order) that I need to add as soon as I (we) figure this problem out.

I commented out most of the function, but I get the same results with the whole function too. I guess I’m getting leftover memory, but why?

Line 59 to 62, you ask to get user input, but where do you store them? Also, you don't have pepperoni and cheese initialized but use them in your total cost calculation?
