Calculates the overall grade for four equally weighted programming assignments, where each assignment is graded out of 50 points. Hint: First calculate the percentage for each assignment (e. g., score / 50), then calculate the overall grade percentage (be sure to multiply the result by 100). Calculates the overall grade for four equally weighted programming assignments, where assignments 1 and 2 are graded out of 50 points and assignments 3 and 4 are graded out of 75 points. Calculates the overall grade for a course with three equally weighted exams (graded out of 100) that account for 60% of the overall grade and four equally weighted programming assignments (graded out of 50) that account for 40% of the overall graded. Hint: The overall grade can be calculated as 0.6 * averageExamScore 0.4 * averageProgScore. Extend the program to support the grading scheme for one (or all) of the courses.
