Answer 1

#include<bits/stdc++.h>
using namespace std;
class Vehicle
{
    long int erg_no;
    float cost;
public:
    virtual void start()
    {
    }
    virtual void stop()
    {


    }
    virtual void show()
    {


    }
};
class Heavy : public Vehicle
{
public:
    void start()
    {
        cout<<"\nStart function of Heavy ";
    }
    void stop()
    {
        cout<<"\nStop function of Heavy ";
    }
    void show()
    {
        cout<<"\nShow function of Heavy ";
    }
};
class Lightweight : public Vehicle
{
public:
    void start()
    {
        cout<<"\nStart function of Lightweight ";
    }
    void stop()
    {
        cout<<"\nStop function of Lightweight ";
    }
    void show()
    {
        cout<<"\nShow function of Lightweight ";
    }
};
int main()
{
    Vehicle* v1;
    Heavy h1;
    v1 = &h1;
    Lightweight l1;
    Vehicle* v2;
    v2 = &l1;
    v1->show();
    v1->stop();
    v1->start();
    v2->show();
    v2->stop();
    v2->start();
}
