If you're taking a class, use the compiler that the teacher will be testing you and your programs, with. There are two highly rated free C compilers that I know of. One is Microsoft's Visual Express (Google for a d/l site). The video is helpful to d/l as well.
The other is MingGW compiler, with Code::Blocks IDE. Google "Code::Blocks" for more info.
Turbo C won't handle newer C functions, or large memory demands, but it is simpler to use. It will easily handle simple graphics and non-buffered input, that both the above, will handle only with some difficulty.
Although I can't recommend Turbo C, I confess to using it with pleasure, for small stuff.
