C++ QUESTION

/*This program calculates a students course average using randomly generated grades.

You will need to edit the program where 'FIXME' is noted as well as make some additions to complete the program.

The course weights are based on the actual values from the course syllabus.

*/

/* Calculate the overall course grade & convert it to the appropriate letter grade */

coursePercentage = ((homeworkScore / HOMEWORK_MAX) * HOMEWORK_WEIGHT) // FIXME for all of the syllabus components

+ 0.0 // FIXME for midterm

+ 0.0; // FIXME for final

coursePercentage = coursePercentage * 100; // Convert fraction to %

cout << endl << "Your course percentage (FIXME): ";

cout << coursePercentage << endl;

// Output the users name, their grade for each individual category, and overall grade(number and letter) in the course.

return 0;

}

The grading scale for this course is

3 tests 30%

Final test 15%

In Class Participation 10%

Homework & Challenges* 10%

Labs & Quizzes 15%

Project 20%

A 90-100

B 80-89

C 70-79

D 60-69

F <-60

please use this scale to answer. Donot use A- or a+ or b+

just A,B,C,D,F as mentioned up

90-100 is A donot mention a+ or a- just write a code from 90-100 is A
