8.(a) (i) Explain passing objects and returning object to method with suitable example. (6)
(ii) Differentiate early binding and late binding. (6)
(Or)
(b).Make a class Student. Student class has the data members such as roll number, name, and
branch. Create a class called Exam with data members roll no and six subject marks. Derive
the Result class from Exam which has its own data member such as total marks, average and
grade. Write a program to calculate the grade of a student based on the marks entered by user
in each subject and print the student name and their grade based on this logic.
If the average of marks is >= 90 then prints Grade ‘O’
If the average of marks is >= 80 then prints Grade ‘A+’
If the average is <80 and >=70 then prints Grade ‘A’
If the average is <70 and >=60 then prints Grade ‘B+’
If the average is <70 and >=60 then prints Grade ‘B’
If the average is <60 and >=45 then prints Grade ‘C’
else prints Grade ‘U’
