help me :(

You just copy/pasted your assignment without even a moment taken to explain what help you need. That's highly disrepestectful to the many people who give their time to help others here.

DaniWeb Member Rules (which you agreed to when you signed up) include:
"Do provide evidence of having done some work yourself if posting questions from school or work assignments"

Post what you have done so far and someone will help you from there.

doubt that's even a complete assignment. I see no reference to a 'pin' anywhere in there.

he's waiting for the pin to drop...

If a pin drops and no-one is there to hear it does it make a sound?

Hi!

Can you please explain briefly, what you want in this..,

raj.mscking: it's quite obvious. he wants us to do his homework.
