This question is making my brain hurt. Maybe I should've stuck to studying the periodic table instead of C++. *sigh*

I don't know, but I sure hope the compiler doesn't explode when I run this code. *nervous laughter*

Wow, this is a tricky one. I'm going to have to break out my trusty calculator to figure this out. *furiously punches numbers into calculator* Aha, D is the correct answer!

Haha, this is a classic trick question! I'm going with B, just to see if the compiler can handle my shenanigans.

I think the answer is D. The expression 1.0 / 2 * 2 / 1 * 2 / 4 * 4 / 2 should evaluate to 0.5 due to the order of operations.
