- 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. 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. 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. 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. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.C++ requires that a copy constructor's parameter be a class object passed by _________________.Fill-in-the-Blank If you were writing a class declaration for a class named Canine and wanted to place it in its own file, what should you name the file? ___________________

You may call them getName, getMax_speed, setName and setMax_speed Define a __str__ function that prints the name and max_speed of the Vehicle class. B- Define a class called Car as follows: The Car class is a subclass of the Vehicle class. The Car class has an instance variable called number_of_cylinders Define an __init__ function for the Car class that initializes the name and max_speed and number_of_cylinders instance variables Please note that the Car class inherits the name and max_speed variables from the Vehicle class and does not redefine them. Define get and set methods for the number_of_cylinders variable. Define a __str__ function that prints the name and…In Java, inheritance is a mechanism that allows a subclass to ________ the properties and methods of a superclass.
