A derived class uses a constructor from the base class to initialize all the data inherited from the base class.
False
True
Problem Statement
Design a Mother class that has the following member:
• A virtual printInfo function that displays the class information which is the Class's name.
Design a BabyA class that is derived from the Mother class. The BabyA class should have the following:
• A printInfo function that overrides from the base class. The BabyA
Design a BabyB class that is derived from the Mother class. The Babys
class' print function should display only the class's name.
class should have the following:
• A print Info function that overrides from the base class. The BabyB
class' print function should display only the class's name.
Write a program that has an array of Mother pointers. The array elements should be initialized to Mother, BabyA, and Babys objects. The program should then step through the array with a loop and call each object's printInfo function.
Partial Solution

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• getDiameter.

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, then use the object's accessor methods to retrieve it and display it on the screen.arrow_forwardDefault constructors are inherited from the base class, thereby eliminating the need for derived classes to define their own default constructors.
