In C++, both pointers and references are powerful tools for indirectly accessing and manipulating data. Although they share similarities, their design philosophies and usage are quite different. Understanding these differences is crucial for writing efficient and safe C++ code. Let us delve into the key distinctions between references (int& ref) and pointers. Basic Concept Analysis … Read more

In the vast realm of embedded development, the C language shines like a brilliant star, holding a crucial position. For beginners with no background in embedded systems, mastering the core syntax of C is undoubtedly the key to unlocking this technical door. Today, we will focus on the extremely important structure part of the C … Read more
In the C language, the “interchangeability” of arrays and pointers refers to the high consistency in syntax and behavior between the two in specific scenarios. However, this consistency does not stem from their inherent similarity, but is determined by the array name decay rules, syntax design, and compiler processing logic in C language. This article … Read more

The Design Philosophy of C Language The design philosophy of C language can be summarized as “Trust the Programmer“. Unlike many modern programming languages, C language imposes very few restrictions on the behavior of programmers, assuming that programmers know what they are doing. Thus, C language is actually a language that demands a lot from … Read more
