The first posting's output and this may vary since that was developed with XCode 3 and this one with XCode 4. There are slight differences between both of them, but that we don't want to know. You can download XCode 4 for $5 from Apple's website.
I wanted to keep this final section very light. Hence going to show only the output here. :)
