From Macroscopic to microscopic understanding of coding, macroscopic and microscopic coding Macro thinking is to have a clear understanding of what we do and understand what we are pursuing. After understanding the whole, we need to have a deep understanding of what we are interested in. This is the so-called micro-thinking. The old saying "not seeking the whole, not seeking a domain" is the same. I persona

Reprinted please indicate the source: http://blog.csdn.net/horkychen (Excerpt from msdn-coding techniques and programming practices) Names) Naming is most helpful for understanding the logical structure of a program. 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. Network Engineer ExaminationAnd related materials: Bit CenterThe
