thank you for doing yet another lazy kiddo's homework for him, potentially creating yet another clueless, lazy, colleague for someone, somewhere.

he'd still fail his assignment as there no doubt is a lot more wrong with his code that he's too lazy to and/or incapable of figuring out for himself and is therefore waiting for us to spoonfeed him....

and no, we're not going to do your homework for you.
You tell us what you think is wrong, and someone might tell you whether you're right or not.
