Delving into Object‐Oriented Programming

In this chapter, the authors delve into the domain of the object‐oriented (OO) approach to software design and object‐oriented programming (OOP), which helps with software system modeling. They delve into the OOP properties of C++, starting with OOP concepts and then examining code examples. OOP is based on the four principles: encapsulation, inheritance, polymorphism, and abstraction. The authors provide a closer look at the internal structure of a class. The construction portion of the class contains the special member functions: default constructor, parametric constructor, copy constructor, assignment operator, and destructor. A class's data and member functions can be assigned to the private or public groups. If not explicitly assigned, then by default, members of a class are private. The authors explain how to make another class, this time to represent complex numbers: two valued entities with their own arithmetic rules, which are used e.g. in electronics and physics.
