Map each of the keywords on the left to the statement that describes it the best. Inheritance Class Object Polymophism Instance variable [Choose ] ✓ It is any variable that does not represent a living being. It allows properties and functions to be passed to another object when an object is deleted. It represents a blue print of an object. It is like a global variable that can be accessed in all functions of a program. It is a category to organize variables and objects in groups. It is an instance of a class. It is a programming command with a special meaning. Classes can acquire properties and functions from other classes. It is a property inside that class that exists throughout the lifetime of an object. It is used to define the relationship between classes. It is a variable of a primitive type. It is a variable that can store values of multiple types. It allows a variable of a super class type to be assigned an instance of a subclass type. It is used to describe that a class…

Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.

Chapter 10 defined the class circleType to implement the basic properties of a circle. (Add the function print to this class to output the radius, area, and circumference of a circle.) Now every cylinder has a base and height, where the base is a circle. Design a class cylinderType that can capture the properties of a cylinder and perform the usual operations on the cylinder. Derive this class from the class circleType designed in Chapter 10. Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Also, write a program to test various operations on a cylinder.

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.
is the term used to describe the process of making an instance of one class a member of another.
py You want to initialize parts of a class definition once at the time a class is defined, notwhen instances are created.
