- The single most important reason to use Encapsulation is to reduce a program's complexity.
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.
- The first reason is to provide a simplified and understandable way to use your object without the need to understand the complexity inside.
- The second reason for hiding complexity is to manage change.
