Structural Design Patterns in Modern C++ - Introduction to the Decorator Pattern

The video tutorial discusses the Open Closed Principle, highlighting the limitations of modifying existing code and the static nature of inheritance. It introduces the decorator pattern as a solution, allowing dynamic addition of behaviors to objects at runtime without modifying existing code. The tutorial explains the intent, structure, and implementation of the decorator pattern, emphasizing its flexibility and runtime capabilities. It also briefly compares the decorator pattern with the strategy pattern, noting their differences in altering object behavior.
