Recently, a fan asked me: “Why is the size of the structure I defined always larger than the sum of the sizes of its member variables?” Don’t worry, this isn’t the compiler “stealing memory”; it hides an important concept—byte alignment. Today, we will explain this using the logic of “arranging books on a shelf” so … Read more
Abstract: This article first analyzes the traps and defects of the C language, summarizing the common mistakes; it discusses the shortcomings of compiler semantic checks and provides preventive measures. Using the Keil MDK compiler as an example, it introduces the features of this compiler, its handling of undefined behavior, and some advanced applications. Based on … Read more
Go is a new generation programming language that combines the rapid prototyping advantages of Python with the performance benefits of C/C++. This characteristic makes it suitable for the embedded field as well, but what factors need to be considered to achieve optimal usage? Generally speaking, the most important evaluation aspects for correct operation include the … Read more
