Hi Idiot PHP
what did you do during your lectures / tutorials / school classes? Have you gone back to your teacher / lecturer for any guidance, there's a real good reason for doing this, if you have attended all your classes and are not in a position to even attempt it then either the teaching was poor and they (either the teacher or institution) need to improve it urgently.

BTW the forums generall don't assist with homework.
