Person Data and Customer Data classes and accessor and mutator functions using C++

PersonData and CustomerData classes
Design a C++ class named PersonData with the following member variables:
• lastName
• firstName
• address
• city
• state
• zip
• phone
Write the appropriate accessor and mutator functions for these member variables.
Next, design a class named CustomerData, which is derived from the PersonData
class. The Customer Data class should have the following member variables:
• customerNumber
• mailingList
The customerNumber variable will be used to hold a unique integer for each customer.
The mailingList variable should be a bool. It will be set to true if the customer
wishes to be on a mailing list, or false if the customer does nor wish to be on
a mailing list. Write appropriare accessor and mutator functions for these member
variables. Demonstrate an object of the CustomerData class in a simple program.

PersonData and CustomerData classes

#include <iostream>

#include "CustomerData.h"

// Function prototype

int main()

   // Create a CustomerData object and pass arguments
   // to the constructor.
   CustomerData customer1("Smith", "Joan", "123 Main Street",
                          "Smithville", "NC", "99999", 12345,
                          true);
   
   // Display the object's data.
   cout << "Customer #1\n"
        << "-----------\n";
   displayCustomer(customer1);
   
   // Create another CustomerData object using the default
   // constructor and mutator functions.
   CustomerData customer2;
   customer2.setLastName("Jones");
   customer2.setFirstName("Jenny");
   customer2.setAddress("555 East Street");
   customer2.setCity("Jonesville");

   cout << "Customer #2\n"
        << "-----------\n";
   displayCustomer(customer2);
   return 0;
