Identify ‘Inheritance’ shown in following figure. Implement it by using suitable member function.


C++ Practical






#include <iostream>
using namespace std;

class student
{
public:
    int roll_no;
    char name[10];
    void set_roll()
    {
        cout << "Enter the Roll No & Name of Students\n";
        cin >> roll_no >> name;
    }
    void get_roll()
    {
        cout << "Roll No = " << roll_no << "\nName = " << name << "\n";
    }
};

class test : public student
{
public:
    int oop_marksdsu_marks;
    void set()
    {
        cout << "Enter the marks of OOP & DSU\n";
        cin >> oop_marks >> dsu_marks;
    }
    void get()
    {
        cout << "Marks of OOP = " << oop_marks << "\nMarks of DSU = "  
        << dsu_marks << "\n";
    }
};

class result : public test
{
    public:
    int total;
    void display()
    {
        get_roll();
        get();
        cout << "Total = " << oop_marks + dsu_marks << "\n";
    }
};

int main()
{
    result student;
    student.set_roll();
    student.set();
    student.display();


Output:



Enter the Roll No & Name of Students 25 xyz Enter the marks of OOP & DSU 89 80 Roll No = 25 Name = xyz Marks of OOP = 89 Marks of DSU = 80 Total = 169
