c using polymorphyism create an inheritance hierarchy for t

c++

using polymorphyism , create an inheritance hierarchy for the following types of insurance :

Home, vehicle , life

2 member functions should be included:

- calcpremium

- Home- 0.5% of the value of the home

- Life- 1% of the value of the policy

- Vehicle - 0.5% of the value of the policy

calcCommission

Home- 0.2% of the value of the home

Life- 1% of the value of the policy

Vehicle - 0.5% of the value of the policy

in main

1. instantiate an object for each type of insurance policy.

- Home: value is $457,999.00

- Life: policy value $1,000,000.00

- Vehicle: policy value is $25,000.00

2. Call a global function ( exercising polymorphism) to print out the premium

and commission for each policy.

3. make sure that objects of the base class cannot be instantiated.

#include <iostream>
using namespace std;

//base class to hold insurance details

//functions expected to be overridden by child classed

    }
    double calcCommission()
    {

    }
};

//main function which triggers the class
int main()

   Insurance *i;

   //declare objects of three classes
   Home home(457999);
   Vehicle vehicle(25000);
   Life life(1000000);

   //assign home object to base class object
   cout<<\"\ ***Home Insurance****\";
   i=&home;
   i->display();

   //assign life object to base class object
   cout<<\"\ ***Life Insurance****\";
   i=&life;

   //assign vehicle object to base class object
   cout<<\"\ ***Vehicle Insurance****\";
   i=&vehicle;
