The Relationship Between .h Files and .c Files When referring to the programs of experts, I found that the strict programs written by others all include a “KEY.H” file, which defines the functions used in the .C file, such as Keyhit(), Keyscan(), etc.The .H file is a header file, probably meaning ‘Head’, which is necessary … Read more
Introduction C++ is a powerful and widely used programming language that combines the efficiency of C with the flexibility of object-oriented programming. This article will introduce several fundamental concepts in C++: namespaces, input/output, basic variable types, and control flow. Mastering these concepts is crucial for further learning in C++ programming. 1. Namespaces Namespaces are a … Read more
Over the years, I have seen too many on-site programs, especially in the area of PLC sequential control, where the choice of variable types is poor, leading to numerous pitfalls. A few days ago, I went to a food factory to troubleshoot, and the program almost drove me crazy. They used a bunch of BOOL … Read more

Last week, I helped a colleague solve a problem with his temperature control system on the production line, which was frequently malfunctioning. After some investigation, it turned out that the variable type was not selected correctly, causing the decimal part to be truncated. This incident reminded me that we must discuss the topic of variable … Read more
