There's rarely a total ordering called "better" amongst programs that
solve some problem.  Here you prevent the program from being used as a
filter which matters to me.  (I see from another reply that it
matters much less to you.)

Why is this loop not clearer and/or more intuitive (in your mind) using
your extra eof() function?  Genuine question.  I know it may sound like
a facetious question, but I really am asking.  I don't see why the
arguments you advanced in the other thread do not apply here.

Here I'd also end the loop on EOF.  This is another of my reasoning
issues.  For every loop I see I try to prove that it will always
terminate.

If you do add the EOF check, it's a good idea to guard the whole
prompting part with

  if (!feof(stdin) && !ferror(stdin)) ...

(I'd remove it all, but presumably you need this on a system with no
simple way of paging output.)
