PROGRAMMES ON INHERITANCE:
Take a class ‘student’ having datamember name,rollno.then derive a class ‘exam’ having marks in 3 subjects.
Then derive a class ‘result’ from ‘exam’and take a new class ‘sports’.sports class assigns a grade if a student has some sports activity
.so the final result is a combination of subject marks and sports grade.define suitable conversion table(like sports grade ‘O’
means +20,grade’A’means +10 etc)and display the the result of some student after necessary input.use suitable parametrized constructors.
