Subject: Re: displaying user inputed arrays

Ok im trying to check how many words the user inputs to see if its to 
many like this (>>)

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

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

ive tried many things including putting it after 
input_word.each_with_index do |word, i| and if i is > 5 then do whatever 
but i cant figure it out whats wrong with what is going on now because 
it seems like its saying get the index of how ever many there are and 
get the length of the index ( i think i could have just done index but i 
was trying this when i decided to post this ) and if it is greater then 
5 dont allow it and i looked at a array tut and you can do that with 
index or maybe even with indexes

why doesnt it work?
