Wrong regexp anyways.  That should have been more like...

array = (gets.scan /[\w'-]*/) - [""]
if array.length == 5
  #do something
else
  #do something else
  #for just printing it out
  #puts array or puts array.join(' ')
end

I think you get the general idea, though.  The #scan method is doing
the iterating for you (no need for while loop).
