There is an old saying:“A good memory is not as good as a bad pen.” This saying is equally true in the programming world. The code we write may be forgotten by ourselves months later, and to avoid future frustration, we need to learn to use a very important tool——comments。 01 What are comments? The“invisible … Read more
① The Compilation Process of C Language.c files are transformed into executable files through four stages: preprocessing, compilation, assembly, and linking.(1) Preprocessing: Includes header file inclusion, macro replacement, conditional compilation, and comment removal.(2) Compilation: The C language is translated into assembly, outputting a .s assembly file;(3) Assembly: The assembly file is translated into binary, outputting … Read more
I am Lao Wen, an embedded engineer who loves learning.Follow me, and let’s become better together!Today, we will discuss the status of the C language in the field of embedded technology.In the embedded technology ecosystem, the combination of “C language + hardware” is like “binary + transistors” in computer technology, serving as the foundational cornerstone … Read more

In the last lesson, we used the metaphor of “Hundred Family Surnames” to easily grasp the basic rules of C language identifiers. We learned that names must start with a letter or an underscore, can be followed by numbers, but cannot use keywords. However, this is just the “beginner’s guide” to the art of naming … Read more
