This is an CPU sheduling algorithm i.e proirity sheduling .It show some error that i can't solve please anyone correct it . its very urgent.

This is an CPU sheduling algorithm i.e proirity sheduling .It show some error that i can't solve please anyone correct it . its very urgent.

1) This is not a CODE SNIPPET. Do not post questions as such
2) Help Me is a title in violation of the Forum Rules. You did read them as requested, right?
3) How do you expect anyone to follow unformatted code? Formatting is necessary when writing code.
4) Nothing is urgent on this forum. If it's really urgent, talk to your instructor.
5) You expect us to figure out what your error is with no information from you? Presumptuous, isn't it?
6) You expect us to fix your code for you? Contact hire-a-coder.
