A class Student has Roll No, Branch, class Internal_exam has sub1marks, sub2 marks, class External_exam has sub1marks and class Result has Total as data members. Write necessary member functions to input and print data. (i) Calculate Internal_exam and External_exam subtotals using their respective member functions. (ii) Class Result has a function to calculate Total=internal+ external subtotals. Write a complete program to implement the hierarchy of the classes using virtual base class.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
A class Student has Roll No, Branch, class Internal_exam has sub1marks, sub2 marks, class External_exam has sub1marks and class Result has Total as data members.
Write necessary member functions to input and print data.
(i) Calculate Internal_exam and External_exam subtotals using their respective member functions.
(ii) Class Result has a function to calculate Total=internal+ external subtotals.
