Create a Shape class which must be abstract since we are not going to create any instance of this class. Provide data members for storing area and volume in this class. Provide a virtual function for displaying the data members of this class, a virtual function for computing volume of a shape, and a virtual function for computing area of a shape.Derive two abstract classes TwoDimensional and ThreeDimensional from this class. Provide a virtual member function to display whether an object is 2-dimensional or 3-dimensional. Also include virtual area and volume functions so these calculations can be performed for objects of each concrete class in hierarchy. Implement the hierarchy and write a main program to test the polymorphic behavior of this class.define class by considering the followings: Enlist data members and methods with access specifies. Consider the polymorphism technique for the use of function overriding. Enlist constant and static…Read the following description carefully: In a Course Management System, the class Course has the following attributes: courseCode, courseName, credit and courseType.

- Here question 1. ---Downdog Yoga Studio offers five types of classes, as shown in the Table Attached. Design a program that accepts a number representing a class and then displays the name of the class. b. Modify the Downdog Yoga Studio program so that numeric class requests can be entered continuously until a sentinel value is entered. Then display each class number, name, and a count of the number of requests for each class.Object Oriented Programing Consider the following details of all classes in diagram A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classes.Create a UML class diagram for the following problem: The McDonald’s company has several restaurants in Budapest. Each restaurant has a unique ID and an address. They sell cheeseburger for 500 HUF, BigMac for 1000 HUF, and Chicken McNuggets for 800 HUF. All three can be ordered alone or in small, medium, or large menu. The different menus mean French fries and drink in addition. The small menu costs 500 HUF, the medium is 700 HUF, and the large is 1000 HUF in addition. The customers get a loyalty card from the McDonald’s company which has a unique number. Based on the card, it can be got what kind of foods were ordered by that guest in the different restaurants. Make it possible to populate this problem: create methods to add new restaurant, customer, loyalty card, and orders related to any of the cards.Is it true that each restaurant of the company has a guest who has spent more than 10000 HUF?How much has a guest spent in a given restaurant?How many guests have spent more than 10000…
