Granted, I am very much the Newbie and have yet to progress beyond the most simplistic programs, yet I don't know what one really uses C for.
It does math functions I see. Prints stuff to your screen in a command window (I am using m$)...ummm. After that I don't know.
I suppose I would like to know what kind of programs are built using C and what other lovely things it does/can do.
