Answer 1

#include<iostream>
#include<bits/stdc++.h>
using namespace std;


class Student{
	public:
		int reg_no;
		string name;
		
		void input()
		{
			cout<<"Enter student name : ";
			string s;
			cin>>s;
			name = s;
			cout<<"Enter student regd number : ";
			int n;
			cin>>n;
			reg_no = n;
			cout<<endl<<endl;
		}
		
};


class Exam : public Student{
	public:
		int sub1;
		int sub2;
		int sub3;
		
		void input1()
		{
			cout<<"Enter student marks in sub1 : ";
			int a;
			cin>>a;
			cout<<"Enter student marks in sub2 : ";
			int b;
			cin>>b;
			cout<<"Enter student marks in sub3 : ";
			int c;
			cin>>c;
			sub1 = a;
			sub2 = b;
			sub3 = c;
			cout<<endl<<endl;
		}
		
		
};


class Sports : public Student{
	public:
		int indoor;
		int outdoor;
		
		void input2()
		{
			cout<<"Enter student marks in indoor games : ";
			int a;
			cin>>a;
			cout<<"Enter student marks in outdoor games : ";
			int b;
			cin>>b;
			indoor = a;
			outdoor = b;
			cout<<endl<<endl;
		}
}; 


class Result : public Exam, public Sports{
	public:
		int total_marks;
		
		int get_total()
		{
			total_marks = sub1 + sub2 + sub3 + indoor + outdoor;
			return total_marks;
		}
		
		
};


int main()
{
	Student s;
	s.input();
	Result ob;
	ob.input1();
	ob.input2();
	
	cout<<"Total marks gained by student is : "<<ob.get_total()<<"/500";
	
}
