Creational Design Patterns in Modern C++ - S.O.L.I.D. Principles - Part I

The video tutorial discusses SOLID design principles, focusing on the Single Responsibility and Open Closed principles. The Single Responsibility Principle emphasizes that a class should have only one reason to change, ensuring each responsibility is in a separate class. An example is given where a class managing notes should not handle their display. The Open Closed Principle states that modules should be open for extension but closed for modification, allowing behavior changes by adding new code rather than altering existing code. An example is provided where a method is modified to prioritize notes starting with an exclamation mark, violating the principle. The correct approach involves using virtual functions to extend functionality without changing existing code.
