C++ Homework. Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries.

a. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables.

b. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables.

***Example***

#include using namespace std; class personType {

public:

void print() const;

void setName(string first, string last);

string getFirstName() const;

string getLastName() const;

personType(string first = "", string last = "");

private:

string firstName;

string lastName;

};

c. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries.

i. Load the data into the address book from a disk.

ii. Sort the address book by last name.

iii. Search for a person by last name. iv. Print the address, phone number, and date of birth (if it exists) of a given person.

v. Print the names of the people whose birthdays are in a given month. vi. Print the names of all the people between two last names.

vii. Depending on the users request, print the names of all family members, friends, or business associates.
