Thread: Tell me about C/C++

Actually I have a question...

I'm learning C++ and right now I'm reading about ++ and --

The example it gives me is this...

Example 1:

Code:

B=3;
A=++B;
// A contains 4, B contains 4

Example 2:

Code:

B=3;
A=B++;
// A contains 3, B contains 4

I don't really understand the whole ++ and -- and how it affects the A and B variables. Can someone explain how it adds up?

Edit: Also, how does all this make up a video game engine?
