Push Inputted Words

ruby-talk
1

I'm trying to make a program that gets you to input words and when you
press enter with nothing typed it sorts them alphabetically. My code
right now is:

words=[]
while words!=''
words.push gets
end
if words==''
  words.sort
end

It runs and asks for words. I assume that it is pushing them into the
array but it isn't stopping and sorting them when there is nothing
inputted by the user. Hope I gave enough information.

As always thanks in advance,
Scott Andrechek

I'm now using this:

words=[]
word = 'any'
while word!= ''
  words.push gets
  word= gets.chomp
end
puts
puts words.sort

but as you might notice this code will skip every second word to find a
matching variable for word :S

Or to void instance variables:

words = []
while (word = gets.chomp) != ''
  words.push word
end
puts words.sort

Denotes an instance variable. Allows you to set the variable in the function
and still access it within the while loop.

Is it too much for you to ignore a thread that you find objectionable?
