Behavioral Design Patterns in C++ - Pros and Cons-Template Method

The video tutorial explains the template method design pattern, highlighting its ability to reduce code duplication by factoring out common behavior into a base class. It allows partial customization of class behavior while maintaining control over the algorithm. The tutorial compares the template method with the strategy pattern, noting that the former uses inheritance and allows partial algorithm changes, while the latter uses composition for complete algorithm variation. The video concludes by emphasizing the template method's alignment with the open closed principle, enabling behavior modification without altering existing code.

Explain how the open-closed principle relates to the template method design pattern.
