Between cab and OOAD (top)

For a while, there has been no updates. There have been too many things in recent projects and there is almost no time to access the Internet. When I first came back from five sets, I made two videos, which were too many. It was very troublesome to modify them. In one breath, I threw them away and pasted them in text format. This example was modified from Microsoft's help, so you can refer to the cab help file. The change I made is simply explained by OOAD. In the past two days, I have received a letter from a friend asking for the follow-up part of this series. I have recently posted some video about cab on the Internet and found that there are many applications and the principle is too small. So I thought about how to prepare the cab in the lower part of the cab and OOAD. It may involve a framework pattern and design pattern. I have been looking for opportunities to talk about UNIT TESTING AND refactoring. They are too important. If you have any comments, please send them to me for further improvement.
