Problem: Calculate and report the average grade for a class.

Discussion: The average grade equals sum of all grades divided by the number of students. We need loop to read and then add $($accumulate$)$ grades for each student in the class. Inside the loop, we also need to total $($count$)$ number of students in the class.

Using the Average Grade Problem, create the following representations:

An Algorithm,

A Flowchart,

The Pseudocode, and

The Hiearchy chart.
