Write a program that reads student scores from a file.

You do not know how many students in the class (therefore in the file)

The program finds the average for the class.

then it assigns the letter grade as follows:

average + 10% and above is A

average and above is B (less than the A grade above)

average - 10% and above is a C (less than B above)

less than average -10% is F

I am using visual studio, c++, and will like to see a reference a working code while doing my own, just as reference, any help would be awsome
