Develop a program to calculate and report the average grade for a class. The process involves accumulating grades and counting the number of students. Create various representations for the solution:

$1.$ An Algorithm: Outline the step$-$by$-$step procedure to calculate the average grade.

$2.$ A Flowchart: Draw a flowchart to represent the process visually.

$3.$ The Pseudocode: Write pseudocode detailing the logic of the program.

$4.$ The Hierarchy Chart: Create a chart showing the program's structure.

For each representation, write $1-2$ paragraphs explaining your thought process. Cite any sources used and format your submission in APA style, including a title and reference page.

Submit both your drawings $($charts$)$ and written document, ensuring they align with the assignment rubric
