- Circle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…arrow_forwardMovie Information Write a class named MovieInfo that holds data about movie. The class should have the following member variables: title: hold movie’s name category: hold movie’s category year: hold released year mins: hold running time in mins. Write a constructor that accepts arguments for each member variable, appropriate mutator functions that store values in these member variables, and accessor functions that return the values in theses member variables. Once you have written the class, write a separate program that creates four MovieInfo objects and stores the following data in them.

- Employee and ProductionWorker Classes Create an Employee class that has properties for the following data: Employee name Employee number Next, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.arrow_forwardwritte in c++ Write a Circle class that has the following member variables: • radius : a double • pi : a double initialized with the value 3.14159 The class should have the following member functions: • Default Constructor. A default constructor that sets radius to 0.0. • Constructor. Accepts the radius of the circle as an argument. • setRadius. A mutator function for the radius variable. • getRadius. An accessor function for the radius variable. • getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radiusarrow_forward(C++) 23. True/False: function getGallons() is an inline member function 24. Design a class called Date. The class should store a date in three private integers: month, day, year. There should be a member function to print out the date in the month/day/year format, e.g. 12/25/2015, 4/1/1970 There should be a constructor which takes three parameters to initialize the date. It should not accept values for day greater than 31 or less than 1, or values for month greater than 12 or less than 1. If the constructor is called with these values an error message should be printed out and the field set to 0. Any value for year is acceptable. There do not need to be any other member functions. Provide the class declaration and also the implementation of the member function and constructor.arrow_forward
- True or FalseA base class reference variable can reference an object of any class that is derived from the base class.arrow_forward(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.arrow_forwardProblem: Employee and ProductionWorker Classes Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker class, and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen Note: The program should be written in python. Sample Input/Output: Enter the name: Ahmed Al-AliEnter the ID number: 12345Enter the department:…arrow_forward
- Write base class with the name Shape . The Shape class have Private Variable: area, a double used to hold the shape's area. Public Member Functions: getArea the Accessor. This function should return the value in the member variable area. Parameterized constructor—Initializes area member. Defualt constructor— Empty body calcArea. This function should be a incomplete function.Next, define a class named Triangle . It should be child of Shape class. It should have the following members:Protected Member Variables: base, a integer used to hold the base of triangle.Height, a integer used to hold the height of the triangle. Public Member Functions: constructor—Initializes values for base, height. The overridden calcArea function in Circle described below.calcArea—calculates the area of the Triangle (1/2* base * height) and stores the result in the inherited member area.After you have created these classes, create a driver program that defines a Triangle object.

Add appropriateconstructors, accessor functions, and mutator functions. Also define a functionnamed getLifespan that returns a string with the value “unknown lifespan.” Next, define a Dog class that is derived from Pet. The Dog class should have aprivate member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors.Redefine the getLifespan function to return “Approximately 7 years” if the dog’sweight is over 100 pounds and “Approximately 13 years” if the dog’s weight isunder 100 pounds. Next, define a Rock class that is derived from Pet. Redefine the getLifespanfunction to return “Thousands of years.” Finally, write a test program that creates instances of pet rocks and pet dogs thatexercise the inherited and redefined functions. use c++arrow_forward
