USE PYTHON PROGRAMMING LANGUAGE(OOP) 1. (Geometry: n-sided regular polygon) An n-sided regular polygon’s sides all have the same length and all of its angles have the same degree (i.e., the polygon is both equilateral and equiangular). Design a class named RegularPolygon that contains: ■ A private int data field named n that defines the number of sides in the polygon. ■ A private float data field named the side that stores the length of the side. ■ A private float data field named x that defines the x-coordinate of the center of the polygon with a default value 0. ■ A private float data field named y that defines the y-coordinate of the center of the polygon with a default value 0. ■ A constructor that creates a regular polygon with the specified n (default 3), side (default 1), x (default 0), and y (default 0). ■ The accessor and mutator methods for all data fields. ■ The method getPerimeter() returns the perimeter of the polygon. ■ The method getArea() returns the area of the…

(Package Inheritance Hierarchy) Use the Package inheritance hierarchy created inExercise 19.9 to create a program that displays the address information and calculates the shippingcosts for several Packages. The program should contain a vector of Package pointers to objects ofclasses TwoDayPackage and OvernightPackage. Loop through the vector to process the Packagespolymorphically. For each Package, invoke get functions to obtain the address information of thesender and the recipient, then print the two addresses as they would appear on mailing labels. Also,call each Package’s calculateCost member function and print the result. Keep track of the totalshipping cost for all Packages in the vector, and display this total when the loop terminates.

(Polymorphic Application) You’ve been asked to develop a flight simulator that will haveelaborate graphical outputs. Explain why polymorphic programming could be especially effectivefor a problem of this nature.

Describe how memory allocation is done to objects and also develop a C++ programfor employee class with following attributes such as Employee ID, Employee Name,Designation and Salary. Program should sort and display the list of employees inascending order of their salaries using object as a function argument. (Note:Employee ID must not be inputted by the user i.e., auto incremented.)

(The MyDate class) Design a class named MyDate. The class contains: The data fields year, month, and day that represent a date. month is 0-based, i.e., 0 is for January. A no-arg constructor that creates a MyDate object for the current date. A constructor that constructs a MyDate object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. A constructor that constructs a MyDate object with the specified year, month, and day. Three getter methods for the data fields year, month, and day, respectively. A method named setDate(long elapsedTime) that sets a new date for the object using the elapsed time. Draw the UML diagram for the class and then implement the class. Write a test program that creates two MyDate objects (using new MyDate() and new MyDate(34355555133101L)) and displays their year, month, and day. (Hint: The first two constructors will extract the year, month, and day from the elapsed time. For example, if the elapsed time is 561555550000…

(In C++) Part 1: Write a program that tracks employee information. The program should use classes for employee records. Each employee should have a record containing the following information: - First Name - Last Name - Phone Number - Address - City - State Zip - Position - Job title - Payment type - The program should be able to allow for the following: - the input of new employees, - display of existing employees, - editing existing employees, - deleting employees. To display payment type/salary This must calculate pay for either an hourly paid worker or a salaried worker. Hourly paid workers are paid their hourly pay rate times the number of hours worked. Salaried workers are paid their regular salary plus any bonus they may have earned. The program should declare two structures for the following data: - Hourly Paid: - - HoursWorked - - HourlyRate - Salaried: - - Salary - - Bonus The program should ask the user whether he or she is calculating the pay for an hourly paid worker or…

(Operator Overloads in Templates) Write a simple function template for predicate functionisEqualTo that compares its two arguments of the same type with the equality operator (==) andreturns true if they are equal and false otherwise. Use this function template in a program thatcalls isEqualTo only with a variety of fundamental types. Now write a separate version of the program that calls isEqualTo with a user-defined class type, but does not overload the equality operator.What happens when you attempt to run this program? Now overload the equality operator (withthe operator function) operator==. Now what happens when you attempt to run this program?

(Using C++) Define a base class vehicle and its two derived classes :Car and Scooter. Write a program to ask the user for the type of vehicle and then using the concept of runtime polymorphism, display the message "It is a two-wheeler" for scooter and "It is a four-wheeler" for car.

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…
