Rating of a Score in Java
Machine Problem
Create a simple program that will determine the rating of a score
Rating
46 - 50 -> Excellent
41-45 -> Outstanding
36-40 -> Very Satisfactory
31 - 35 -> Satisfactory
Other values -> Out of rating
Output
Enter Score : 45
Your Score is 45 and equivalent rating is Outstanding.
