We are NOT here to do your homework for you and i REALLY hope that nobody here actually gives you these answers sorry but thats the truth. Now if you would post questions(SPECIFIC QUESTIONS) along with source code of what you currently have we may help you without writing your code for you. and dont try saying you dont have time because i dont want to hear about how your procrastination is about to make you fail this assignment.

Kindly,
TJ

It appears that you chose to seek help far too late (what with time-zones and everything), and your first port of call should have been in any case your tutor and your classmates.

You should have at least posted your current solution attempt. The fact that you did not rather suggests that you have in fact made no attempt whatsoever.
