// Program to demonstrate multiple inheritance

// Don't use two base classes, instead use an interface.

// HW -

// WAP which implements hybrid inheritance in which create a class student with data, roll no, name.

// Create another derived class as test, which uses the base class student

// and will accept the 3 subject marks from the user which will contain the function as reading, displaying the student details

// Create interface sports, which will initialize sports marks

// Another class test which extends the test class and implements the sports interface for calculating the total marks for the student

// Base class - student

// Two derived classes - test, result (extends test and implements sports class)

// Check for hierarchical inheritance (create another class for competitive exams)
