Subject: Ruby Nuby Question

Hello,

I am just learning Ruby, via several resources (online: Why's,
downloaded PDF's, and Chris Pine's book "Learn to Program Ruby").  I
finished Chris Pine's book and was going back through doing any of the
exercises I hadn't done the first time and trying to mess with/break the
programs I had done the first time through.

In looking back over my code and trying to clean things up, I managed to
think of two good questions I can't seem to find the answer to
elsewhere.  I figured this was the brightest and smartest group of
Ruby-heads out there. :)

I'll ask my questions first and put the code from the program down
below.  The assignment asked us to create a "Deaf Grandmother" program,
which you could only get out of by saying "BYE" to in all caps, three
times.

The first question I had was, for some reason, if you input "BYE!" for
the second or third required "BYE" (to exit/end the program), it
launches into an infinite loop.  Why is that?  BYE works correctly.
What is it about "BYE!"?

Second question is... what if I wanted the program to require you to say
"BYE" three times in a row instead of just three times throughout the
conversation.  Is there any easy way to do this?


Okay, thanks for your time, the code from the program is below..

[code]
talk = 'I <3 my grandmother'
puts 'WHAT A FINE YOUNG GRANDCHILD YOU ARE, COME TO VISIT YOUR DEAR OLD
GRANNY!  COME IN, COME IN!'

while talk != 'BYE'
talk = gets.chomp
  if talk != talk.upcase
    puts 'HUH?!  SPEAK UP, SONNY!'
  elsif talk == talk.upcase && talk != 'BYE'
    year = 1
    while year < 30
      year = rand(51)
    end
    puts 'NO, NOT SINCE 19' + year.to_s + '!'
  end
end

if talk == 'BYE'
  puts 'WHAT WAS THAT?'
  talk = gets.chomp
  while talk != 'BYE'
      if talk != talk.upcase
        puts 'HUH?!  SPEAK UP, SONNY!'
      elsif talk == talk.upcase && talk != 'BYE'
        year = 1
        while year < 30
          year = rand(51)
        end
        puts 'NO, NOT SINCE 19' + year.to_s + '!'
      end
  end

  if talk == 'BYE'
      puts 'EYE?  WHAT\'S WRONG WITH YOUR EYE?'
      talk = gets.chomp
      while talk != 'BYE'
          if talk != talk.upcase
            puts 'HUH?!  SPEAK UP, SONNY!'
          elsif talk == talk.upcase && talk != 'BYE'
            year = 1
            while year < 30
              year = rand(51)
            end
            puts 'NO, NOT SINCE 19' + year.to_s + '!'
          end
      end

      if talk == 'BYE'
        puts 'OH VERY WELL, SEE YOU ANOTHER TIME, THEN!'
      end
  end
end
