- 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.THIS QUESTION IS RELATED TO SUBJECT OBJECT ORIENTED PROGRAMMING IN C++ .

Also write the setter/getter, default and parameterized constructor in each class. Write a main which create object of derived class and call all inherited function of base class. Note: Each class should have atleast two attribute of base classUsing C# Language: Programming PLO 3 Measured: Create control structures, methods with the appropriate parameters, and data structures of the appropriate type, and implement algorithms to solve problems. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class. Write another class named Subcontractor that is derived from the Contractor class. The Subcontractor class should have member variables to hold the following information: Shift (an integer) Hourly pay rate (a double) The work is divided between two shifts, a day shift, and a night shift. The shift variable will hold an integer value representing the shift that the subcontractor will work. The day shift is 1 and the night shift is 2. Write one or more constructors and the appropriate accessor functions for the class. Demonstrate the classes…Write the program of object oriented programming c++. Declared Rectangle(Data Members: Length and width) as a friend class of Square(Data Member: int side). Thus now, all the functions of Rectangle can directly access any private member of Square.In the main function, the first statement created an object 'square' of the class Square, thus calling its constructor and assigning 5 to its data member side.The second statement in the main function created an object 'rectangle' of the class Rectangle.In the third statement, 'rectangle' called the function shape() with the object of the class Square passed as its argument. In the 'shape()' function, the value of 'side' (private data member of Square) was assigned to length and breadth. The fourth statement called the function 'getArea' of the class Rectangle.
- Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.The class Item has the following private member variables Data Type Variable Name string itemId string itemName string itemType string itemVendor Include appropriate setters and getters for the above class. Include the following constructors in the Item class Constructor Name Description Item( ) This default constructor used to initialize the itemType as “Electricals” and itemVendor as “Arun electricals” Item(string itemId,string itemName,string itemType,string itemVendor)…Use C++ Create a class called Fruit. Add one member variables name. Add only one getter function for the name. The get function returns name. Implement a constructor that expects name value and assigns it to the member variable. This class doesn't have an empty constructor. Create a subclass of Fruit named CitrusFruit. The CitrusFruit class has two member variables weight and color. Add a constructor which expects weight and name and color.Pass name to the base constructor and set weight and color to it's member variable. Write a program that has an array of 3 Fruits, and an array of 3 CitrusFruits. Feel free to give the name , weight and color to the object as your choice. Use loops to print out the array properties to the terminal screen.you will design various classes and write a program to computerize the billing system of a hospital.a.

- Program SpecificationUsing python, design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables: customerNumber mailingList The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables. Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…Write a C++ program. Define a class called HourlyEmployee that inherits the Employee Class provided. The class must have private attributes to store the total hours worked, the total regular hours worked (sum of hours ≤ 40), and the total overtime hours worked (sum of hours > 40).The class must also have member functions to perform the following tasks:• A constructor to initialize the first name, last name, and pay rate (See the Employee Class for more details).• A setter function to set the hours work for the month (by the week – assume 4 weeks in a month). Do not write separate setters for total regular and total overtime hours. Use a while/for loop that iterates four times to read the hours worked from the user and call the setter function four times. The header of the member function should look like this:void setTotalHoursWorked(double hoursWorked)• A getter function to return⬧ the total regular hours work for the month⬧ the total overtime hours for the month⬧ the monthly…Using C++ write a class named Point with the following specification: (a) In a .hpp file declare Point class which must 3 private data members which are doubles named m_x, m_y, m_z which initialized via the class’s constructor that should take 3 parameters in the .cpp file. (b) Point class should have 3 const accessor instance functions to get the x, y and z co-ordinates of the Point object. (c) Create a main function in the main_func.cpp file and instantiate a point p1 with the following x and y co-ordinates: x should be 7.86, y should be 8.786 and z should be 9.786. (d) Instantiate a further 6 Point objects using a for loop with random x, y and z double data type co-ordinates in the following ranges with the decimal portion of the random numbers being non-zero. x range -100 .0 < x < 100.0 y range -50.0 < y < 50.0 z range -25.0 < z < 25.0 (e) Using cout object print out the values of each of the 7 Point objects you have created in main using the…
