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.

Expert Solution

#include <iostream>
using namespace std;

//base class to hold insurance details
class Insurance
{
public:

//declare variables
int value;

//functions expected to be overridden by child classed
virtual double calcpremium()=0;
virtual double calcCommission()=0;

//global function to display insurance details
void display()
{
     cout<<"\nValue: \t\t"<<value;
     cout<<"\nPremium: \t"<<calcpremium();
     cout<<"\nCommission: \t"<<calcCommission();
}
};

//home insurance class
class Home:public Insurance
{
    public:
    Home(int v)
    {
        value=v;
    }
    double calcpremium()
    {
        return value* 0.5/100;
    }
    double calcCommission()
    {
        return value*0.2/100;
    }
};

//vehicle class
class Vehicle:public Insurance
{
    public:
    Vehicle(int v)
    {
        value=v;
    }
    double calcpremium()
    {
        return value* 0.5/100;
    }
    double calcCommission()
    {
        return value*0.5/100;
    }
};

//life insurance class

class Life:public Insurance
{
    public:
    Life(int v)
    {
        value=v;
    }
    double calcpremium()
    {
        return value* 0.1/100;
    }
    double calcCommission()
    {
        return value*0.1/100;
    }
};

//main function which triggers the class
int main()
{
    //delcare insurance object
   Insurance *i;

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

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

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

   //assign vehicle object to base class object
   cout<<"\n***Vehicle Insurance****";
   i=&vehicle;
   i->display();
   return 0;
}

Sample Output:

***Home Insurance****

Value: 457999

Premium: 2289.99

Commission: 915.998

***Life Insurance****

Value: 1000000

Premium: 1000

Commission: 1000

***Vehicle Insurance****

Value: 25000

Premium: 125

Commission: 125

In c++, when dealing with inheritance in a class hierarchy, a derived class often has the opportunity to overload or override an inherited member function. What is the difference? and which one is the better?

Using C++ Create a polymorphic banking program using the Bank-Account hierarchy created in Exercise 2 of Written Assignment 4. For each account in the vector, allow the user to specify an amount of money to withdraw from the Bank-Account using member function debit and an amount of money to deposit into the Bank-Account using member function credit. As you process each Bank-Account, determine its type. If a Bank-Account is a Savings, calculate the amount of interest owed to the Bank-Account...

Java Code: Problem #1: Create an inheritance hierarchy of Rodent: mouse, gerbil, hamster, guinea pig. In the base class, provide methods that are common to all rodents based on behaviours you find with a quick Internet search. Be sure to document the behaviours you implement (e.g., eat, sleep, groom, move, etc.). Each behaviour should print its action to standard output (e.g., rodent eating). Next, refine these behaviours in the child classes to perform different behaviours, depending on the specific type...

Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate. Two-Bit Drilling Company keeps information on employees and their insurance dependents. Each employee has an employee number, name, date of hire, and title. If an employee is an inspector, then the date of certification and the renewal date for that certification should also be recorded in the system.
