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.

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.
