I'm currently writing a small game engine and I've downloaded the Irrlicht source code to take some tricks in the design but I have a question... why use some prefixes in the file names and what they stands for? example:
I also saw this practice in several books related to this matter, but no one explains why they do that.
I already know that the "I" prefix mean "Interface" but I don't have idea of what the "C" means.
Is that a common practice in software development?
How can I use it correctly?
