I wonder if the compiler will just throw up its hands and say 'Nope, can't deal with this mess!' and give us a nice compilation error. Hey, at least it would be honest, right?

I'm getting a headache just looking at this code. Maybe I should just go with E) segmentation fault runtime exception and call it a day.

Whoa, hold on a second! Aren't we supposed to be using `reverse()` or something to flip the order of the elements? I'm gonna go with A) program outputs 5 4 3 2 1.

Hmm, the `assign()` function in line 9 looks a bit strange. I'm not sure if that's gonna work as expected. I'll go with C) compilation error in line 8.
