Model a room class, whose member data is three integers length, width and height. The classcontains two constructors to initialize the room class objects, first is no argumentconstructor, while the second in three arguments constructor. Class also contains threemember functions i.e., getdatat) to get the data from user and store in the memory of callingobject and showdata) to show the room data of calling object, int volume(int I, int w, int h)function should receive the length, width and height values from the objects one by one andreturn the volumes of the three objects respectively.Write a main program to declare the three object rl, 12, and 13 of room class. Two objectwill store the values through three argument constructor and third object will get the datafrom user by calling getdata function. Then all three objects should call the volumefunctions to calculate their volumes and store them in three variables of type integer. Finallythe system compare the three volumes values…
Let us create the shape class hierarchy. 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…

a.Define the class pointType to implement the properties of a point in a two-dimensional plane. Your class must contain functions to individually set and retrieve the x and y coordinates, find the distance between this point and another point, and constructors to initialize pointType objects. If p1 and p2 are pointType objects, then p1.distance(p2) returns the distance between p1 and p2.b. Write the definitions of the member functions of the class pointType defined in part a.c. If we know two points on a line, we can describe various properties of a line, such as whether the line is vertical, horizontal, or slanted, and if the line is nonvertical, then find its slope. Define the class lineType with two private data members of type pointType to store the coordinates of two points on a line in the two-dimensional plane. Among others, your class must contain functions to determine if the line is vertical, horizontal, or slanted, find the slope of the line, and output the equation of the…

One hour income is Rs. 150 • Similarly, PermanentEmployee class has function named calculate_the_income to calculate the income of an employee that gets paid the salary for exact 240 hours, no matter how many actual hours he or she worked. Again, one hour salary is Rs. 150.Implement all class definitions with their respective constructors to…
This lab will exercise your understanding of some of the concepts covered in Chapter 13:overloading operators 1. Create a class, name of your choice, to represent a college class in which students might register. a. Create three private member variables:Class Name (to hold values such as CSC210)Number of StudentsClass Hours b. Overload the >> operator to input, from cin, into the class object, the Class Name and Class Hours c. Overload the << operator to output all the private member variables d. Overload the + (plus) operator to add a value to the Number of Students private member variable.This will represent students registering for the class. e. Overload the - (minus) operator to subtract a value from the Number of Studentsprivate member variable. This will represent students dropping the class. f. The default constructor should initialize the private member variables appropriately. 2. Write a client program to: a. Upon program execution, create one class object that…

Create a base class named Point consisting of x and y data members representing point coordinates. From this class, derive a class named Circle with another data member named radius. For this derived class, the x and y data members represent a circle’s center coordinates. The member functions of the Point class should consist of a constructor, an area() function that returns 0, and a distance() function that returns the distance between two points,(x1,y1) and (x2,y2), where Additionally, the derived class should have a constructor and an override function named area() (PI*pow(radius,2)) that returns a circle’s area. Task: 1-Include the classes constructed in a working C++ program. 2-Have your program call all the member functions in each class. 3- In addition, call the base class’s distance() function with two circle objects and explain the results this function returns.

In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
