Create a modular program that will accept the inputs for assignment grade (4 inp

Question

Create a modular program that will accept the inputs for assignment grade (4 inputs), lab test grades(3 inputs), lecture test grades(4 inputs), postlab grades(9 inputs) inputs, quiz grades(9 inputs) and clicker grad from the user. The program then provides the following menu to the user. Write different functions to implement the functionality of this program to compute the expected values.

1. Show the Grades in a Tabular Format

2. Show the Overall Grade (number and letter)

3. Exit if any other input

Enter your choice:_

The grades are calculated based on the following breakdown:

Assignments 1-4 Each 5% Total 20%

Lab Tests 1-3 Each 10% Total 30%

Lecture Tests 1-4 Each 10% Total 40%

Post Labs 1-9 Each .3% Total 2.7%

Quizzes 1-9 Each .4% Total 3.6%

Clickers Total 3.7%

The letter grade is calculated as below:

90-100= A

80-89 = B

70-79 = C

60-69 = D

0-59 = F
Your program should ask the user for the scores based on the above data. Then, the final score will be calculated and printed in Here is an example run: Enter the score for the first assignment: 89.5 Enter the score for the second assignment: 85 Enter the score for the third assignment: 86.90 .......... The Overall Grade is 86.5. Letter Grade: B
