No, it was done in C#, and even if it was in C, it's not worth the trouble to preprocess the code anyway. The assignment answers were usually simple but short. Something like sorting a linked list using insertion sort. If you have no idea how linked lists work, it's likely you would copy it. But if you understood linked lists, and already knew insertion sort, you could probably write it on the spot within 20 minutes.

Wow, so you never had to write complete programs for assignments? That "write a sort function" question seems more suitable to what I'd expect on an exam. You find out who knows/doesn't know a lot faster than a homework problem where you may be able to program it at the time but don't understand in general only to fail on the next exam, or maybe you think you know it already so you just copy from somewhere and change variables, but don't really know it, and so you also fail at test time.

Bleh. The whole point of catching plagiarizers has been to determine whether work was done in some expected way, not to make sure learning happened or anything useful came from the work.
