Look if you just want somebody to do all your homework for you without any effort on your part then piss off and don't come back here again you lazy little waste of space.  If you are willing to listen to people and put some effort in then we can help you but you need to start doing a bit of the some work and not simple cutting and pasting the question over and over again.  It's your choice but I do not expect anyone else to help you if you do not start showing some attempt to do it yourself.
