Design a class named Square that defines a square geometric shape. The class needs to have a data member named side that defines the length of each side. Then defined two member functions: getPeri and getArea to find the perimeter and area of the square shape. Now define a Cube that defines a cubic shape and inherits from the Square The class Cube needs no new data members, but it needs the member functions getArea, and getVolume. Provide the appropriate constructors and destructors for both classes.

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.
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.
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…
Consider a base class named Employee and its derived classes HourlyEmployee and PermanentEmployee while taking into account the following criteria.• Employee class has two data fields i.e. a name (of type string) and specific empID (of type integer)• Both classes (HourlyEmployee and PermanentEmployee) have an attribute named hourlyIncome• Both classes (HourlyEmployee and PermanentEmployee) have three-argumentconstructor to initialize the hourlyIncome as well as data fields of the base class• Class HourlyEmployee has a function named calculate_the_hourly_income to calculate the income of an employee for the actual number of hours he or she worked. 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…
Q3 Use the concept of polymorphism and classes to represent the following analog A Transportation class has the fields (model, year) with all the setters and getters. An Airplane class inherits Transportation, and it has a field number of wings (no wings) with a setter and a getter. A Car class inherits Transportation, and it has a field number of wheels (no wheels) with a setter and a getter. Al the parent and child classes have toString( ) method that prints everything. In the main program, create an array of transportations of size 6 (3 of them are airplanes and 3 are cars), and put any values you choose in the constructors. Finally run a loop through the array and print all the information, and by using the tool “instance of” if the element is an airplane, print “BINGO..AIRPLANE”, if the element is a car, print “BINGO..CAR”
Create a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape. Instantiate objects of both Circle and Triangle classes, and demonstrate the usage of the overridden area() functions.
Write a class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.
Create a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape. Instantiate objects of both Circle and Triangle classes, and demonstrate the usage of the overridden area() functions. Expand the Shape hierarchy by adding a new class Square. Override the area() function in the Square class to calculate the area of a square. Create a function named calculateTotalArea() that takes an array of pointers to Shape objects and calculates the total area of all shapes using polymorphism.
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…
