Never, never, never, *never* use gets(). Period.
See http://www.eskimo.com/~scs/C-faq/q12.23.html
(Read the whole FAQ, while you're at it, the returns
are well worth the effort imo.)

Use fgets(), which does feature a parameter with which
you can restrict the amount of input text stored.

Since it's outside control of the language, you'll still
need to deal with any possible 'extraneous' input that
might still reside in an OS's input buffer. Just use a
loop which extracts characters until a newline or EOF is
encountered.
