actually this doesnt work the way i want it to.

when i try to retrieve and array  from that i think that the scan thing 
returns it as a integer other then the string i need why is this?

this is the code that im using to do this:

places = ['first', 'second', 'third', 'fourth', 'fifth']
puts 'Please enter 5 words on the same line with spaces then press 
enter:'

answered = false
while not answered
input_words = (gets.scan /[\w-]*/) - [""]
  if input_words.length > 5
    puts "Please type in FIVE words no more: "
  else
    answered = true
  end
end

input_words.each_with_index do |word, i|
  puts "To view a word you picked type:\n 1: first word\n 2: second 
word\n 3: third word\n 4: fourth word\n 5: fifth word"
  answered = false
  while not answered
  num_answer = gets.chomp
    case num_answer[0]
      when '1'[0]
        i = 0
        answered = true
      when '2'[0]
        i = 1
        answered = true
      when '3'[0]
        i = 2
        answered = true
      when '4'[0]
        i = 3
        answered = true
      when '5'[0]
        i = 4
        answered = true
      else
        puts "Try again...enter a number 1 - 5 to see one of the words 
you typed"
    end
  end
  puts "The %s word you entered was %s" % [places[i], word[i]]
end
