- 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.arrow_forwardQuestion 14 papa .use python Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this linearrow_forwardAn interface is a collection of _______ that a class can implementarrow_forward

I'm still new to programming and not very good with object programming. I was wondering if I could get some insight on how this is structured.arrow_forwardObjectives By completing this assignment students should be able to: • Write programs using classes Instructions Write a program called passport.cpp. You also need to create a class to hold the passport itself. This class should be broken into .epp and .h files as we have done in class. The license class should hold the following information about a license: • The passport number • The first and last name of the person • Their nationality • Their birthdate You will then write a program that will prompt for information about a person's passport and then print out that license to the command line. Sample Output what is the person's first name: James What is the person's last name: Bond what is the passport number: 28128555 what is the person's nationality: UK What is the person's birthdate: 01/01/1970 UK Passport: 28128555 James Bond Born 01/01/1970arrow_forwardLab 2 – Designing a class This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab. Design a class named Computer that holds the make, model, and amount of memory of a computer.

Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method…arrow_forward5. class definition for GameEnemy Next, we want to start making enemies for our upcoming video game, so we will define a class called GameEnemy. Every GameEnemy will have a name, an x location, a y location, and a number of hit points (which must be a non- negative integer ). The_init__ method for GameEnemy will take all of these parameters (in that order) and store them on the object. GameEnemy also needs a method called healthbar, which will allow us to show that enemy's health bar in the game. It returns the enemy's name followed by a number of asterisks to show how many hit points it has left. The exact format is shown below. Sample runs should look like: >>> enemy = GameEnemy ("TODD", 100, 200, 5) >>> enemy.healthbar() TODD: ****** >>> enemy-% ence 100 >>> enemy-y 200 If vou havo qu octionaarrow_forward
