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

Is it asked too much that you read the first seven paragraphs  
before posting?

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