Only if they were using polymorphic data structures. But most of the Real World uses null-terminated data structures instead, despite that approach's practical disadvantages, so students need to learn how to work with them too -- and CS2 seems like an appropriate place to do that. So yes, they WOULD have a conditional for the outer part.
