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.

What is the role of the abstract base class in the template method pattern?

Describe the structure of the algorithm as defined by the template method pattern.

Explain the significance of the optional step in the template method pattern.

How does the subclass interact with the primitive operations defined in the base class?

What precautions are taken to prevent clients from invoking primitive operations directly?
