The implementation of the system function requires the following steps. First, the rough framework is designed, then the code is written according to the system requirements, then the program is debugged, and finally the system is summarized. The most important of these is the two steps of writing code and debugging the program. In this design, what impressed me the most was the debugging of the system. During the debugging process, I encountered a lot of problems, but after I kept checking the information, the teacher's guidance, and the classmates' discussions, these problems were gradually solved.
