Awesome C Exam Question

Working through some C example exam questions for my exam on Thursday Friday and @andyide found this little beauty.

Without cheating and running it through gcc, give it a dry run and see what you get. My first attempt was incorrect with 4 12 -1 16. Gutted.

(EDIT: For anyone who was wondering what the answer actually was, without compiling, click here. I didn’t want to post the spoiler in the post. That wouldn’t be any fun.)
