Question

Getting stuck on chapter 8:

Type as many words as we want
One word per line, continuing until we just press Enter on an empty line
Repeats the words back to us in alphabetical order.
Use ‘sort’

So, here’s what I got to, but I’m having funny issues with not getting the first word to push into the array [among other things]

# alphabetting

puts 'Tell us some of your favorite things!'

# create an array
words = []

while gets.chomp != ''
  words.push gets.chomp
  words.sort
    puts words 
end

Did this and it works now… Do I have to have “thing” in there though? Seems naughty to assign within a ‘while’ loop.

puts 'Tell us some of your favorite things!'

words = []
puts words

while (thing = gets.chomp) != ''
  words.push thing
end

puts words.sort 

Answer 1

Your first gets call is not referred to by anything, and is thrown out. It is not just the first word, but every other word that is going to be thrown out. The output routine should also be outside of the loop. A fix is:

words = []
while word = gets.chomp and not word.empty?
  words.push(word)
end
puts words.sort
