Behavioral Design Patterns in C++ - Spreadsheet Application - V

The video tutorial explains the dependency inversion principle and how to avoid tight coupling by using a base class for different format classes. It introduces dependency injection, highlighting the benefits of setter injection over constructor injection. The tutorial demonstrates implementing a CSV format export using the strategy pattern, which allows for dynamic strategy selection at runtime. It also shows how to add support for HTML format export, emphasizing the advantages of composition over inheritance for creating flexible and maintainable code.

What is the consequence of tightly coupling the data model class with the CSV format class?
