Mith, being an engineering professional myself, I have to say that it''s pretty difficult to come up with good interview questions. As it happens, this is a great interview question (IMHO), and I''ll probably steal it in the future if we ever start hiring again. Maybe you missed the original thread that stated this was a question asked in an interview.

Yeah Mith, I agree, I''d request that anyone who used something like this be shot also, but it was an interview question. And I''d have to say it''s a pretty good one for an interview, shows you how quickly someone can analyze what is going on and tests their knowledge of pointers and arrays etc.
