Behavioral Design Patterns in C++ - Basic Implementation-Template Method

The video tutorial explains the template method pattern, starting with the creation of an abstract base class that defines the template method and primitive operations. It discusses how clients can modify the algorithm by implementing subclasses and overriding specific steps, while some steps remain fixed. The tutorial also highlights the importance of preventing clients from directly invoking primitive operations by declaring them as protected. Finally, it presents a class diagram to illustrate the pattern's structure.
