please optimize my code

I have attached my project for the current semester but before submitting it I want it to be optimized.
I mean the same output but with better code, shorter, faster, or more effecient.

could anyone try to test it and optimize it as possible as he can and then post it here for me

I am going to submit it on 17 may 2002

please try your best

thanx in advance
