1. create a C++ program having 3 functions:

(1) functionA calculates the total score of a student taking CSC001.

The course includes:

- two quizzes - the full score of each quiz is 10 points, and the weight is 5%.

- two assignments - the full score of each assignment is 100 points, and the weight is 10%.

- a midterm exam - the full score is 50, and the weight is 10%.

- a final exam - the full score is 100, and the weight is 40%.

- a project - the full score is 25, and the weight is 25%.

- The score of each coursework is passed to the functionA by one function parameter.

That is, functionA has 7 parameters representing the score of various coursework.

- After the total score is calculated, functionB is called by functionA that will calculate and return the letter grade (represented by, such as A, B, C, D or F).

- Finally, functionA will print the total score and letter score.

(2) functionB has one parameter and will return a value when it is done. When functionB is called, based on the total grade from step

(1), function B calculates and returns the letter grade to functionA.

The rules are listed below:

- A 90% - 100%

- B 80% - 89%

- C 70% - 79%

- D 60% - 69%

- F 0% - 59%

(3) call functionA in the main method
