Using int main instead of void main
saying std::cout, etc instead of using namespace std
banishing system for cin.ignore or getch

Ah, ok. So there's no real performance difference.

Jumping on with what everyone else is saying, and completely agreeing with Jani here:

In my personal opinion, every single function you code should always return a value. No matter how big or small the function is, or what it says. There will always be a reason why that function can fail. (I know a lot of people will disagree with this, but it is my opinion.) Nothing inside a computer is perfect, and something can cause an error in the most uncommon of places. I prefer to at least use a boolean return, or a hresult, for any function I write unless it needs a different return value.

For the namespace, as Jani said, there is no reason to include the entire namespace in your project. Just wasting resources doing that. Unless you really plan to use like.. every single piece of the namespace in a project, theres no reason for you to include it. Just take the time to type out the std::

You load so much more things into the memory of your program just by calling that 1 line. You are already using the iostream, take advantage of whats already given to you to accomplish the same thing with less of a footprint.
