Creational Design Patterns in Modern C++ - Singleton Issues

The video tutorial discusses the issues associated with the Singleton design pattern, particularly its violation of the dependency inversion principle and challenges in unit testing. It demonstrates a basic implementation of a Singleton class called 'local printer' and highlights the problems of direct usage in code. To address these issues, the tutorial suggests using inheritance to create a more flexible design that allows for different types of printers and easier unit testing with mock objects. The approach enhances flexibility and adheres to better design principles.
