Behavioral Design Patterns in C++ - Change Manager - I

The video tutorial explains the observer pattern, initially with a single subject, and then addresses the challenges that arise when multiple subjects are involved. To manage dependencies between subjects and observers, the change manager is introduced as a mediator, following the mediator design pattern. The change manager handles notifications and maintains mappings, reducing the need for direct dependencies. The tutorial concludes with a preparation for implementing this pattern in code.
