- Inheritance is a white box approach to design where composition is black box. We want black box design if possible because it better decouples our code. We should thus favor composition over inheritance. True/FalseInheritance is an OOP concept such that a class can be defined in different ways, such as either being typecasted to itself (as a subclass) or any of its superclasses. True FalseClasses: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…

- Why is it not recommended to code under the finalize method of a class which executes when the garbage collector reclaims memory of an object of a class?Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add reference declarator (& before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.please answer with proper explanation and step by step solution. Question: Program in python: Design a simple class called Dealership, that has two functions: buyCar(Car a) and sellCar(Car a). buyCar(Car a): Adds the car to the list of cars already in the dealership. sellCar(Car a): Removes the car from the list of cars already in the dealership. Note: Implementation of the Car class is not important for this question
- Laguage: C++ Explain youre answer. True or False? - For class inheritance, field initializer is just an efficient opinion for the constructor of the derived class, but we dont necessarily need it.Overriding a superclass function means we can change the throws clause. Is this possible?Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.
