ah to hell with it, there was a trick hiding in those questions and I have absolutely no idea how to do question 4 with just a basic stdio.h header -__- It’s past the deadline by > 30 mins I give up.  I’ll borrow a friend’s to see where I went wrong..

NVM, gonna study math propositional logic and algorithms and Unix instead, and maybe finally memorise the number systems conversion properly gahhh I need to ace something.

Sorry Mr Teach.  and you’re my personal tutor too oh shoot. I’LL DO BETTER FOR THE NEXXXTT ONE  where we can use the standard library headers…
