01. Encapsulation


  • The single most important reason to use Encapsulation is to reduce a program's complexity.

Encapsulation Objects

Encapsulation: C vs C++

  • By default, C struct members are public.
  • With a C++class, the default is private.
  • Classes are essentially private structures.
  • C++ uses public interfaces (member functions) to access the private data (member data).
  • Classes and structs behave identically.
  • When you create an object in an object-oriented language, you can hide the complexity of the internal workings of the object.
  • As a developer, there are two main reasons why you would choose to hide complexity.
    1. The first reason is to provide a simplified and understandable way to use your object without the need to understand the complexity inside.
    2. The second reason for hiding complexity is to manage change.
