OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- True or False Polymorphism allows a class variable of the base class type to reference objects of either the base class or the derived class types.Public members of a base class can be accessed by anything from outside the base class. Private members can be accessed only by the base class and derived classes. Protected members can be accessed by the base class and any of its descendants (child class or child of a child class). answer choices True FalseO Polymorphism allows the addition of classes providing they were at least considered during program .development
- If a class inheriting an abstract class does not define all of its functions then it is known as? a) Abstract b) A simple class c) Static class d) None of the mentionedProgramming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…A derived class’s constructor explicitly invokes its base class’s constructor,but a derived class’s destructor cannot invoke its base class’s destructor.Why does this apparent asymmetry make sense?
- is the term used to describe the process of making an instance of one class a member of another.If a class is derived privately from the parent class then . Select one: a.all members are accessible by the child class b.no members of the base class is inherited c.all the members are inherited by the child class but are inaccessible d.the compiler gives an errorPure Abstract Base Class ProjectDefine a pure abstract base class called BasicShape. The BasicShape class shouldhave the following members:Private Member Variable:area, a double used to hold the shape's area.Public Member Functions:getArea. This function should return the value in the member variable area.calcArea. This function should be a pure virtual function.Next, define a class named Circle. It should be derived from the BasicShape class. Itshould have the following members:Private Member Variables:centerX, a long integer used to hold the x coordinate of the circle’s center.centerY, a long integer used to hold the y coordinate of the circle’s center.radius, a double used to hold the circle's radius.Public Member Functions:constructor—accepts values for centerX, centerY, and radius. Should callthe overridden calcArea function described below.getCenterX—returns the value in centerX.getCenterY—returns the value in centerY.calcArea—calculates the area of the circle (area = 3.14159 *…

Select one: a.the compiler gives an error b.all the members are inherited by the child class but are inaccessible c.no members of the base class is inherited d.all members are accessible by the child classDefine a class called master that inherits data members andfunctions from graduatestudent class, and then declare thefollowing data member: - int newid.Member function:- constructor- set and get function for the data member- Print function.Object Oriented Programing Consider the following details of all classes: Person Student Employee Administration Dean/HOD A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classes
