Question

Hello, I am trying to calculate a student current average in a class based on their Quiz, Homework, Test, Project, and Final Exam grade. Quizzes are worth 20% of the grade. Homework is 15% of the grade. Tests are 35% of the grade. Projects are worth 10% of the grade and the Final Exam is worth 20% of the grade. The program reads how many quizzes, tests, homework, and projects the user enters and the scores that are entered by the user. However, the average is computed before the final exam is taken so the relative weights of the other categories will need to be adjusted. Therefore, the program is only computing quizzes, tests, homework, and projects. How would I compute the average? Please use c++ coding. Thanks!
