Programming Assignment 12

Write a program to process an arbitrary number of student grades. It should do the following:

1. Read in each student's name and three exam scores.

2. Calculate the average of the three exam scores (use a function).

3. Calculate the letter grade based on the following table (use a function):

Average Grade

90 - 100 A

80 - 89 B

70 - 79 C

60 - 69 D

0 - 59 F

4. Print the name, letter grade, and a bar graph representing the average score for each student. ( Use a function to print the stars.)

5. Print the class average, highest average, lowest average, and the total number of A's, B's, C's, D's, and F's.

Your program should read until it runs out of data in the input file.
