fscanf(), fgets(), fflush() problem

Wrong: fflush() forces the stdio implementation to flush its internal buffer,
whether it be block-buffered, line-by-line, or none, by doing (for example) a
write() system call.  After that, the operating system can do what it likes in
buffering data to be written to a terminal, file, pipe, or whatever.


An alternative to using scanf() and fscanf() on interactive input is to use
fgets(), and then sscanf() the resulting string.  I think this is an FAQ.
