Answer to Question #280809 in C++ for amna

Question

Write a program having a base class Student with data members

rollno, name and Class

define a member functions getdata() to input values and another

function putdata() to display all values. A class Test is derived from class

Student with data members T1marks, T2marks, T3marks, Sessional1,

Sessional2, Assignment and Final. Also make a function getmarks() to

enter marks for all variables except Final and also make a function

putmarks() to display result. Make a function Finalresult() to calculate

value for final variable using other marks. Then display the student

result along with student data.
