Just as a sidenote: there's nothing C++-specific in your question
at all. It's all about plain C.

The real problem is in your belief that fflush(stdin) does anything
predictable, which it doesn't. It's one of the typical 'DOSisms' you
find in badly written books about C and/or C++.

The proper method to flush an input stream is to write a small loop
that behaves like this:

	while ((dummy = getchar()) != EOF)
	  ; /* do nothing, just loop */
