concretebuilder from forgetting to write certain functions that cause a lack of arms in the case of a missing leg.The last question naturally is why use dependency, in fact this is also better answer, because we want to generate a product. At the same time we can conclude through this dependency that the builder pattern is encapsulated on the basis of product, which means that we do not like to change the product but instead call the Porduct method.T

C + + Builder as a RAD tool for program development, its new visual programming environment, component-oriented development model will undoubtedly greatly improve the programming efficiency. It encapsulates the intricacies of Windows messages and APIs, and programmers in most cases ignore the details of Windows messages as long as they focus on the component's event-handling functions. However, after all, the Windows operating system is a message-driv
