Computer Fundamentals and Programming 2
Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules:
- If the average score is equal or greater than 90, the grade is A.
- If the average score is greater than or equal to 70 and less than 90, the grade is B.
- If the average score is greater than or equal to 50 and less than 70, the grade is C.
- If the average score is less than 50, the grade is F.
