Inadvertently, I went from the Internet to an ebook, "24 design patterns and six design principles". I'm curious that there are 24 design patterns here, the Design Patterns written by GOF seems to have only 23. At first glance, it really attracted

Command mode: encapsulate a request as an object so that you can parameterize the customer with different requests, queue requests or record request logs, and support unrecoverable operations. It should be a relatively simple mode.  12. 1.

Decoration mode, dynamically add some additional responsibilities to an object. The Decorator mode is more flexible than the subclass generation function.13. 1. Explanation Main (), Dad ISchoolReport, transcript Interface CFourthGradeSchoolReport,

17. 1. Explanation Concept: Multiple objects have the opportunity to process requests to avoid coupling between request senders and receivers. Connect these objects into a chain and pass the request along the chain until an object processes it. Main
