Explain the use of wrapper classes for non-object data types, so those wrapper methods can be implemented alleviating the issues of mixed non-object values with object-related values.

Both abstract classes and interfaces may be used to express common object behaviour.What factors should you consider when deciding whether to utilise an interface or 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.
