Be careful with your counts.  Most people would say that a 30
character words needs a 31 character array to store it.  I'd say
your code accepts words up to and including 29 characters.

This is underspecified.  At least in one sense, if "anything else
beyond" has been discarded, how can there be any more input?  Maybe
you want to throw away any more input on that line?

You can't change the Ctrl-D behaviour without resorting to some
serious OS-specific code.  You may need a screen library like ncurses
if you go much further.
