I. Functions Use a prototype instance to specify the type of the object to be created, and copy the prototype to create a new object. Ii. Structure Diagram Iii. Advantages and Disadvantages Advantage: copy itself. The customer does not know the

The plug-in technology is used in applications to facilitate later version updates, maintenance (such as patching), and function expansion. It is a very practical technology.The biggest feature is that you do not need to recompile the main program
