Behavioral Design Patterns in C++ - Document Framework - III

The video tutorial discusses implementing data versioning in files, focusing on updating version numbers and handling data changes without altering the base class interface. It highlights issues of code duplication in file handling and introduces the template method design pattern to streamline processes, allowing subclasses to focus on data-specific operations while avoiding repetitive code.

Describe the motivation behind implementing the template method design pattern.

How do template methods help subclasses in managing their data?
