All member variables should - in most cases - be declared with this access specifier.   public   private   package   none of the above

Which statement of the following is the most appropriate? Group of answer choices When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the botttom of the implementation file for easy reference. When you design a class, always make an explicit statement of the rules that dictate how the member variables are used.

When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the top of the implementation file for easy reference.

Describe how you can use an interface as an alternative to a class to specify the type for a parameter.

Classes: 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…
