Thanks

Short Answer: By default STDOUT is usually unbuffered. If this is a problem for you, there is fflush(stdout); but that is rarely needed

You didn't give a language, but assuming that you're using C's stdio functions (fopen() etc.) or a language that uses these (and most do, for portability reasons):

It depends on the underlying C runtime library.

Most libraries will try to detect whether STDOUT is connected to a terminal, and avoid buffering if so, and perform block buffering (e.g. my Linux system buffers 8Kb at a time) if not.
