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:

- C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…Default constructors are inherited from the base class, thereby eliminating the need for derived classes to define their own default constructors. O True O FalseUsing classes and arrays, the team will develop a set of functions for an onlineshopping system. The system is represented by the following structure:1- Class Item having the following private attributes: (ID, name, quantity, price) andthe following public methods:- Constructors (default, parameterized, and copy)- Setters & Getters- Operator overloading for the ==, +=,-=, >> and << operators Note that the ID member variable is not entered or read from the user. It isautomatically set by the class as a serial ID starting with the first item of ID 1 andincrementing with every new object.2- Class Seller having the following private attributes: (name, email, items,maxItems),where items is a dynamic array of objects of type Item with the size maxItems. Theclass has the following public methods:- Constructor (parameterized)- Operator overloading for the insertion << operators- Add An Item.- This will take an Item object as a parameter:- If the item already exists in the…
