The sports class inherits student class and consisting of data members such as sports_ mark. The statement class inherits the data members of sports class and used to find the total and average of a student.

Answer 1

#include <iostream>
using namespace std;
class Student{
    public:
    int rno, mark1, mark2;
    Student(int no, int m1, int m2){
        rno = no;
        mark1 = m1;
        mark2 = m2;
    }
};
class Sports : public Student{
    public:
    int sports_mark;
    Sports(int no, int m1, int m2, int m3) : Student(no, m1, m2){
        sports_mark = m3;
    }
};
class Statement : public Sports{
    int total;
    float average;
    public:
    Statement(int no, int m1, int m2, int m3) : Sports(no, m1, m2, m3){
        total = mark1 + mark2 + sports_mark;
        average = total / 3;
    }
    void display(){
        cout<<"Total = "<<total<<"\nAverage = "<<average;
    }
};
int main(){
    int rno, mark1, mark2, sports_mark;
    cout<<"Enter student rno: ";
    cin>>rno;
