Software Engineering: Summary of C coding practices, and summary of c CodingExperiment 4: the reusable linked list module is used to implement the experiment requirements of the command line menu applet V2.5. The Reusable linked list module is used to implement the command line menu applet. When executing a command, a specific function is called as the execution action. The interface design of the linked list module must be general enough, the func

A name description is "what" is more important than "how. Naming can avoid exposing the underlying implementation, thus retaining an abstract layer, simplifying the complexity of the program. For example, you can use getnextstudent () in

Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities: 1.
