return stack[++top] = newItem; will increment top before returning the stack value.

Do you know the difference between ++top and top++?

Yes, well? That's what the language description says. Honestly, there are plenty of reasons C++ is evil, but having increment operators that do what the spec says they'll do is not one of them. That's rather an example of what we call an eye-dee-ten-tee error.

stack[top++] = newItem; is pretty conventional, and for obvious enough reasons.

I prefer "&stack + (sizeof(newItem) * top) = newItem;", myself. Pointer arithmetic is nifty*

(Yes, I know I've probably screwed that up, my C/C++ is rusty. You get the idea, I hope)

* For all definitions of nifty that imply a certain sort of masochism.

I also get upset when the language works exactly as it is described. For example, did you know that if...then...else control structures won't let you execute both code blocks one right after the other, but rather selects which code block to execute based on the truth value of the boolean expression provided in the if clause. Bastards!

How am I the first person to note that the witch of the north is the good one, while its her western counter part who is evil? Just look at her name,(Glenda the Good!)

Glenda could probably help you out with your C++, she's got some pretty crazy power.

Learn literature/pop culture along with your tech.

I believe he's referring to Canada as "The North". Which doesn't make much sense, since the C++ spec is the same everywhere, but whatever.
