Textbook Question
Chapter 15, Problem 37RQE
Write the declaration for class B. The class’s members should be as follows:
• m: an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B.
• n: an integer. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class B.
• setM, getM, setN, and getN: These are the set and get functions for the member variables m and n. These functions should be accessible to code outside the class.
• cal c: a public virtual member function that returns the value of m times n.
Next, write the declaration for class D, which is derived from class B. The class’s members should be as follows:
• q: a float. This variable should not be accessible to code outside the class but should be accessible to member functions in any class derived from class D.
• r: a float. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class D.
• setQ, getQ, setR, and getR: These are the set and get functions for the member variables q and r. These functions should be accessible to code outside the class.
• calc: a public member function that overrides the base class calc function. This function should return the value of q times r.

Problem: 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:…
T F
The public members of a class may be directly accessed from functions that are inside (part of the class
T F Classes are allowed to contain both functions and variables.
