Write a C++ program to Show grades with marks percentage.

Example of all possible Outputs:

Example Output #1

Enter total marks obtained: 85 Grade: A

Example Output #2

Enter total marks obtained: 95 Grade: A+

Example Output #3

Enter total marks obtained: 70 Grade: B

Example Output #4

Enter total marks obtained: 60 Grade: C

Example Output #5

Enter total marks obtained: 45 Grade: D

Example Output #6

Enter total marks obtained: 30 Grade: F

Example#2

Let us see the C++ program to Calculate the percentage of marks and show grade using the switch statements. Percentage >= 90% : Grade A Percentage >= 80% : Grade B Percentage >= 70% : Grade C Percentage >= 60% : Grade D Percentage >= 40% : Grade E Percentage < 40% : Grade F
