My buddy is in some trouble. He has to translate some coding from C# to C++, but he doesn't know how to do it. And he has to have it finished by tomorrow, which isn't enough time for him to learn how to do that. Can anyone help?

The code:

Some notes he had about it:

-takes list of product codes
-applies formula
-tests if modulate/10 == 0
-valid if does, else invalid

Not sure what any of that means or if its relevant at all (I don't know squat about programming, I'm just trying to be a good friend). Please help!
