Output:

Enter the number of students:
2
Enter the details of student 0:
47 sathish 90
Enter the details of student 1:
55 coderegister 80

Details of student 1
ID=47
Name=sathish
Percentage=90
Grade=O

Details of student 2
ID=55
Name=coderegister
Percentage=80
Grade=D

Implementation:

/* Grades are calculated based on the percentage of marks: 1. Grade O - 90% to 100% 2. Grade D - 80% to 89% 3. Grade A - 70% to 79% 4. Grade B - 60% to 69% 5. Grade C - 50% to 59% 5.
