Structural Design Patterns in Modern C++ - Adding the Shape Base Class

The video tutorial explains how to draw shapes using the Win 32 GDI API with software rendering. It introduces a base class called Shape, from which Line and Circle classes inherit. The Line class is modified to use a shared window, and a Circle class is implemented with position and radius attributes. The tutorial demonstrates drawing these shapes in a shared window and discusses the benefits of abstraction for future extensions, such as adding hardware rendering support.

Describe how the draw method is implemented for both Line and Circle classes.
