Structural Design Patterns in Modern C++ - Shapes Hierarchy and Implementing the Line Class

The video tutorial explains the concept of shape abstraction using classes like Line, Circle, and Rectangle. It introduces the implementation of a line gloss and a window class to facilitate drawing shapes using Win32 GDI. The tutorial covers the creation of a window, the use of methods in a specific order, and the implementation of the Line class with attributes and methods. It concludes with running the application to draw a line and discusses extending the implementation to other shapes like circles and rectangles, which will inherit from a common base class.
