Answer 5

I already insert the first one :)

Answer 6

Which one exactly?

Answer 7

Heres the fix..
Since the sum value after the first loop will have some value,since its life time is throughout the program,its value is continued in the 2nd loop and it messes up the avg of 2nd student loop.
so before starting the 2nd loop initialize the sum=0.
and it works fine..
