    putchar() will do you fine.

    You can do some interesting things with ostreams probably, but only if you're uhmm, interested, and dedicated and such~

    Well if it's just static text, then puts() is a lot better than printf()

    But to be quicker still, you'd need to make your code non-portable and rely on something specific to your OS/Compiler.

    if you use c++ you some implementations of std::cout are faster than printf().

    Well that's not the real answer, but scroll down to the windows version of clrscr(), then go and read those and the related functions on MSDN for accessing the console directly.
