- Programming Language = Python 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: • Employee name • Employee number Next, write a 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 rate The 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 each class. Once you have written the classes, 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 and then use the object’s accessor methods to retrieve it and display it on the…arrow_forwardPerson and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.arrow_forwardemployee and production worker classes write an employee class that keeps data attributes for the following pieces of information: • employee name • employee number next, write a 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 rate the 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 each class. once you have written the classes, 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. satak overfallowarrow_forward
- If Lawyer is a subclass of superclass Employee. There is a user-defined constructor Employee(int age), define the constructor in the Lawyer class that would use the constructor Employee(int age) in the superclassarrow_forwardWe discussed in the class that during the design, you may need a class that serves as an interface for its derived classes, but you would not create any instance of that class. Such a class is called an abstract class. The UML class diagram shown below shows a class hierarchy starting from the Vehicle class which is an abstract class. Write a program to implement this class hierarchy such that the given code in the main function runs without error. Vehicle Bus Car Truck IntraCityBus InterCityBus int main() { Vehicle* V[] = { new Bus, new Car, new Truck, new IntraCityBus, new InterCityBus }; for (int i = 0; i < 5; i++) { cout<< V[i]->move() <<endl; } return 0; } Your program should produce an output as the following: Bus: Moves to carry a large number of people Car: Moves to carry a small number of people Truck: Moves to transport goods Intra-City Bus: Intra-City Bus: Moves to carry a large number of people between two areas of a city Inter-City Bus:…arrow_forwardin c++ 3. Develop additional classes for Cat, Horse, and GuineaPig overriding the move() and speak() methods. (If you didn’t know, guinea pigs go “wheep wheepLinks to an external site.”). Make sure to also define a constructor and destructor for each of these classes, and that when you run your program, you can also see that the correct constructors and destructors are being called. Recall that a derived class will always call the parents constructors and destructors, so if you see this behavior, that is okay. Just make sure you are also calling the derived class’ constructors and destructors. Test with the modified main: int main (){Mammal* theArray[5];Mammal* ptr;int choice;for (int i = 0; i < 5; i++){cout << "(1)dog (2)cat (3)horse (4)guinea pig: ";cin >> choice;switch (choice){case 1: ptr = new Dog;break;case 2: ptr = new Cat;break;case 3: ptr = new Horse;break;case 4: ptr = new GuineaPig;break;default: ptr = new Mammal;break;}theArray[i] = ptr;}// Iterate through…arrow_forward
- An employee has a name, phone number and salary. A coach is a person with a senitority status, one of: junior, lead, and senior. Define the possible status values as constants. A staff is a person with a job title and job descrption. Your programming task is to Implement as abstract class named Employee and two subclass name Coach and Staff in Java as defined above Provide constructors for classes to initalize private variable Override the toString() method in each of the classes in task 1 to display the class name and the person's name Write an application to create objects of type Coach and Staff and print the person's name and the class name of the objectsarrow_forward3. Person and Customer Classes The Person and Customer Classes Write a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.arrow_forwardWrite a ¢+ program to define a class called Transporter which has the following data members: passengers: to define the number of passengers. fuelcap: to define fuel capacity in gallons, mpg: to define fuel consumption in miles per gallon. The class should also contains the following functions: range to retum the range that the Transporter can pass. get_passengers to return the passengers. get_furlcap to return the fuelcap, get_mpg to return the mpg. Then define a subclass called Truck from Transporter class which has a data member called cargocap to define the cargo capacity in pounds. Define get_cargocap function to return the cargo capacity in pounds. The Transporter class should a constructor to set its data members. Also the Truck class should have a constructor to set its data members. Build up a main program to create the following objects: Transporter | Type Passengers | Fuelcap | Mpg | cargocap semi | Truck 2 200 7 | 4000 pickup Truck | 3 28 is 2000 minivan | Transporter 7 16…arrow_forward
- Assignment: Write the class XXXX_Worker with constructors, accessors, mutuators, and a toString method. A Worker has a Worker Name and Number. Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift. Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance. Write a class, XXXX_TestWorker, which does the following: Creates one Shift Supervisor object from information entered by the user. Creates an Array of Production Workers that can hold 3 objects.

Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…arrow_forward
