Imagine a publishing company that markets both books and audio-cassette versions of its works. Create a class publication that stores the title (a string) and price (type float) of a publication. From this class derive two classes: book with which adds a page count (type int) and tape which adds a playing time in minutes (type float). Each of these three classes should have a getData() function to get its data from the user at the keyboard and a putData() function to display its data.

- An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 is an arithmetic progression with a common difference of 2.

- Consider a class Movie that contains the following information about a movie. The class has the following attributes: Title MPAA Rating (e.g. G, PG, PG-13, R) Number of people who rated this movie as a 1 (Terrible) Number of people who rated this movie as a 2 (Bad) Number of people who rated this movie as a 3 (OK) Number of people who rated this movie as a 4 (Good) Number of people who rated this movie as a 5 (Great) Implement the Movie class such that it is able to contain the above information. Include constructor that would accept two parameters and initialize the movie's title to the value of its first parameter and the movie's MPAA rating to the value of its second parameter, and public rating to 0. Also include access member functions for title and MPAA rating. Include a member function to increment the public rating that will only accept integer values between 1 and 5. Finally, write a member function that would return the average public rating of a movie. Write a…Imagine a Car Parts and Accessories shop, which requires a software system to keep track of stock items and prices. The shop will sell different kinds of stock items. However, to start with, you have been tasked with designing and implementing a class called StockItem with the following properties. An instance (object) of the StockItem class represents a particular item which the shop sells, with a string representing fixed stock code, an integer representing variable quantity in stock and a double representing variable price of the stocked item. All these variables should be declared as private variables. The StockItemclass also contains a class variable (shared by all instances) of type string representing stock category which you can initialise as 'Car accessories'. A constructor that creates a Stock Item with the specified quantity, price and the stock code. All the appropriate ‘setters’ and ‘getters’ methods, including a getStockName() method which returns the string…This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…

A character instance variable representing a separator (to be used for printing purposes) is also part of the class. The only valid separators we can have are a comma (,), a dash (-), and a pound symbol (#). In addition, a nickname instance variable (string) keeps track of the person's nickname (if any). The output have to match with the image. Write code in JavaScriptYour task is to implement the Name class. This class represents a person's name.

Cars passing by the booth are expected to pay a 50 cent toll. Mostly they do, but sometimes a car goes by without paying. The tollbooth keeps track of the number of cars that have gone by, and of the total amount of money collected. Model this tollbooth with a class called tollBooth. The two data items are a type unsigned int to hold the total number of cars, and a type double to hold the total amount of money collected. A constructor initializes both of these to 0. A member function called payingCar() increments the car total and adds 0.50 to the cash total. Another function, called nopayCar(), increments the car total but adds nothing to the cash total. Finally, a member function called display() displays the two totals. Make appropriate member functions const. Include a program to test this class. This program should allow the user to push one key to count a paying car, and another to count a nonpaying car. Pushing the [Escape] key should cause the…
