Push Inputted Words

Ruby
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

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

Or to void instance variables:

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