imagined. I fully agree with Mr. Yan's point of view. The Code should be reviewed and the specifications should be maintained. 4.7.5 how hard is it to read other people's code? We often complain that it is difficult to read other people's code. When writing code, do we consider how to make the code easier to read and maintain?

inferred prime number, and use the function to implement these two functions. (2) Draw a flowchart of the banking system (the detailed business point ends, not all) Note: in traditional teaching, if you have not learned to write code, you must first learn the painting process. In practice, I felt that the effect was not good. Controls why the structure is dizzy and how it can be drawn. There is a certain programming experience before painting, is t

Top three output test scores for Java programming exercises When I was studying MOOC, I encountered such a Java programming exercise. I checked the Basic Java knowledge I learned: Compile a Java program based on your knowledge to achieve the top three requirements for output test scores: 1. the test scores are saved in the array scores, with the array elements 89
