It depends if you _must_ have 5 words entered or if you just want the
first 5 words.  In either case, look at the many available methods
split, compact, scan.  Also...

((gets.scan /w'*/) - [""])[0..4]

This simply takes all the words typed on a line (a space is a word),
deletes the spaces from the array, and takes the first five.  I like
this better than the gets.chomp.split way because with
gets.chomp.split you will get punctuation (unless that is not
important to you).

With the other way, for example...
words = "hi there, how are you? i'm fine, thanks."

words.chomp.split(" ")
=> ["hi", "there,", "how", "are", "you?"]

Note, the inclusion there of the comma and question mark.
Technically, I would think "you?" is not a word.  Depends on what you
want to do.
