Fair dinkum - how often are you going to keep posting this non-question instead of asking what it is you want to know ? I would hope no-one here would do your homework for you, but everyone would be happy to help if you ask some specific questions about where you are stuck or what you do not understand. Post the damn questions, and I know I will not be alone in being glad to comment. But you should also post your attempts at answers - no-one is going to do your homework for you, and if they did they would be doing you a grave injustice.
