Explain the usage of wrapper classes for non-object data types so that wrapper methods may be built, reducing the problem of mixing non-object and object-related values?

Polymorphism: Why is it needed especially from an OOP standpoint? What is the essential concept when you cast objects regarding Polymorphism/Inheritance? (Related Chapters 11,12,13, 19) Generics: Explain Generic Programming. Why is generics important as a data type regarding objects? Polymorphism and Objects: Explain an array of polymorphic objects in a single/double dimensional array. How do you access this? How do you process this? When would you use this?    Also, when the new topic/chapter is posted regarding File/IO: Write a few lines of code that allow you to save/retrieve this data from a file using the appropriate class/methods. Do this in two ways: StreamFile I/O and URL access. You can also illustrate this in your code via text (.txt) and binary (.dat) data access.  Also, write a few more additional lines of code illustrating StreamFile  I/O access for .txt and .bin files.

Programmers establish classes to maintain a separation between an implementation's function and the data it uses. This directly enables functions and classes to operate on any data type. a false approach would be a file with header information. An illustration of a generic class design format.

Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?

Describe how function objects can be used to implement callback mechanisms.

Both abstract classes and interfaces may be used to specify the behavior of common objects.Which factors should you examine when deciding between an interface and an abstract class?

Introduction The Object Oriented software model is designed to create a new data type by using the Class structure. Therefore the various operations which define a data type, such as the common operators, assignment, etc., have a software architecture available to create those operations and data types. Assignment Description This assignment is an exercise in creating a complete class definition. A standard way to do that is to use a math data type. Here we define a Rational Number data type in a class called “Rational”. The distinctive feature of this type is the data is kept as numerator and denominator throughout all operations; there is no floating point representation used. The standard math operations, addition, subtraction, etc., are implemented, including the iostream overload. The student will not only come to understand what is required for a complete representation of such a type, but also learn about the internal mechanics of its C++ implementation. The student will be…

How can class fields be protected against unintended alteration is the question.

Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?

The book makes the claim that "All built-in data types ... are ADTs". Think specifically about primitive data types (int, char, double, etc.): Do you agree or disagree? If you agree, explain why built-in data types fulfill the definition of an ADT. (Be sure to refer to at least one specific example.) If you disagree, explain why (give an example of a built-in type and why it doesn't meet the criteria for an ADT). (To be clear: "built-in" means part of the language specification and often given special recognition by the compiler. Classes that are part of a language's library -- such as ArrayList in Java -- aren't considered "built-in".)
