Answer to Question #40162 in C++ for Rohit Kumar Srivastava

Question

write a program in C++ to read & display information about institute (Base class) and pupil (Sub-class). using the functions take and display data along with calculating the following:

VARIABLE DATA TYPE MODE CLASS
Name char private base
Regno unsigned long private base
Class char private base
Section char private base
Grade char private base
Phy_mrk int protected base
Che_mrk int protected base
Math_mrk int protected base
Avg_mrk long private sub
Total long private sub

Answer 1

#include<iostream> // cout, cin
#include <cstdlib> // system
#include <stdio.h > // getchar

#define MAX_LENGHTH 255
