I've seen games made in c++ and I was just wonder like say I want to make a game with a rabbit as a character. I don't see how you could make code that makes a character like how do you design what he looks like or what Coleridge he is
In the nicest possible way (which probably doesn't sound very nice, but here it is anyway), based on your other posts, right now they're beyond you in the C++ language.
That said, it depends on your chosen OS. C++ knows nothing about graphics, monitors, or even keyboards. Everything involving that sort of thing is handled by the OS, and in effect you nicely ask the OS to do it on your behalf. This is done using the OS' provided APIs.
There exist a number of libraries that make this easier for you, with the usual tradeoffs. They are popularly known as "widget toolkits" Here is a list of them: http://en.wikipedia.org/wiki/Widget_toolkit
At a lower level than that are the popular graphics APIs such as DirectX and OpenGL. These are much harder than the widget toolkits, but give you a much finer degree of control.
