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

The video tutorial introduces a new document type called 'Numbers', which manages integer data to simplify implementation. It covers methods like 'set number' and 'print', and explains how to override save and load methods. The tutorial also discusses implementing versioning to handle different document versions. Practical use of the Numbers class is demonstrated, and future enhancements are hinted at for managing file versions.

What is the primary data type managed by the Numbers document?

• Boolean

• Float

• Integer

• String

Why is versioning implemented in the Numbers document?

• To reduce file size

• To enhance security

• To support opening documents of different versions

• To improve performance

What should be done before reading the number from a file?

• Check the file size

• Get the version information

• Verify the file path

• Convert the number to a string

What is the purpose of the 'set number' method in the Numbers class?

• To print the document

• To change the number value

• To save the document

• To initialize the document

What is the next step after setting a number in the Numbers class?

• Delete the file

• Print the number

• Save the number to a file

• Load a different document
