- Define a base class shape that includes protected data members for area and volume of ashape, public methods for computing area and volume of a shape, and a display function todisplay the information about an object.Derive a class point from the shape class. This point class contains two protected datamembers that hold the position of point. Provide no-argument and 2-argument constructors.Override the appropriate functions of base class.Derive a class Circle publicly from the point class. This class has a protected data member ofradius. Provide a no-argument constructor to initialize the fields to some fixed values. Provide a3-argument constructor to initialize the data members of Circle class to the values sent fromoutside. Override the methods of base class as required.Derive another class Cylinder from the Circle class. Provide a protected data member forheight of cylinder. Provide a no-argument constructor for initializing the data members to defaultvalues.

- All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.arrow_forward1. Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right, up or down. Each of these four moves should occur with equal probability. The resulting behavior is known as a "random walk." (A 2-dimensional random walk example is pictured at right.) Each Randomwal ker object should have the following public methods. You may add whatever fields or methods you feel are necessary to implement these methods: move () Instructs this random walker to randomly make one of the 4 possible moves (up, down, left, or right). getX () Returns this random walker's current x-coordinate. getY () Returns this random walker's current y-coordinate. getsters () Returns the number of steps this random walker has taken.arrow_forwardPlease do not give solution in image formate thanku.arrow_forward
- Design a class named LinearEquation for a 2 × 2 system of linear equations: The class contains: ax + by = e cx + dy = f ■ Xx= ed - bf ad - bc y = af - ec ad – bc Private data fields a, b, c, d, e, and £. ▪ A constructor with the arguments for a, b, c, d, e, and f. ▪ Six getter methods for a, b, c, d, e, and f. ▪ A method named isSolvable () that returns true if ad – be is not 0. ▪ Methods getX() and getY() that return the solution for the equation. Draw the UML diagram for the class then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that "The equation has no solution."arrow_forwardDefine the class RectangularCube in C++. A RectangularCube has three sides length(L), width (W), and Height (h), define the sides as private data fields. Include a no-argument constructor that sets all three sides to 1. The class must also have a constructor that receive parameters to initialize sides of the RectangularCube. Include get and set functions for all three data fields. Finally define the functions volume () and surfaceArea () in the class RectangularCube that use the formulas given below to calculate and return the volume and the surface area of the RectangularCube. Give the UML diagram of the class, you may use the MSOffice/Visio to create the UML class diagram (best to download and use Visual paradigm tool, or any other free UML tool). Implement the class using separate files for definition and implementation, use inclusion guard to avoid duplicate code. Make sure to include at least one inline function implementation. Do not Implement the volume () and the SurfaceArea…arrow_forward
