Answer 1

#include <iostream>
#include <string>
using namespace std;
class Student{
    int roll_no, age;
    string name;
    public:
    Student(){}
    Student(int roll, int age, string name){
        roll_no = roll;
        this->age = age;
        this->name = name;
    }
    int getAge(){
        return this->age;
    }
};
class UgStudent: public Student{
    int semester, fees, stipend;
    public:
    UgStudent(int roll, int age, string name, int semester, int fees, int stipend):Student(roll, age, name){
        this->semester = semester;
        this->fees = fees;
        this->stipend = stipend;
    }
};
class PgStudent: public Student{
    int semester, fees, stipend;
    public:
    PgStudent(int roll, int age, string name, int semester, int fees, int stipend):Student(roll, age, name){
        this->semester = semester;
        this->fees = fees;
        this->stipend = stipend;
    }


};


int main(){
    PgStudent one(1, 26, "Lucious Fox", 2, 2000, 32),
            two(2, 28, "Robin Johnson", 3, 3222, 7);
    UgStudent three(3, 24, "Robin Johnson", 2, 3222, 2),
            four(2, 22, "Robin Johnson", 1, 3222, 5),
            five(2, 22, "Robin Johnson", 1, 3222, 34);
    cout<<"Average age = "<<(one.getAge()+two.getAge()+three.getAge()+four.getAge()+five.getAge()) / 5<<endl;
    return 0;
