[Image] There is no doubt that C++ is currently the mainstream development language. To learn C/C++, it is essential to build a solid foundation. Their syntax is numerous, and the learning cycle is relatively long, requiring a bit of patience. I was fortunate to study C/C++ for six months in 2015, and after solidifying my … Read more
In C++, when using the <span>getline</span> function to read data that contains <span>0x00</span> (i.e., <span>\0</span>, the null character), issues arise because <span>getline</span> is character-based and will stop reading as soon as it encounters a null character (<span>\0</span>). To read a line that includes the 0x00 character, the following method has been tested and verified to … Read more
In C/C++ programming, function parameter passing is the core method for data interaction between the caller and the callee. Among them, pointer passing and reference passing are key means to “modify external variables through functions,” but there are significant differences in syntax characteristics, memory mechanisms, and usage scenarios. This article will start from the definition … Read more
cwalk is a C/C++ cross-platform library designed for handling file paths. It is lightweight and easy to use, helping developers simplify operations such as path concatenation, parsing, and normalization across different operating systems. To give you a quick overview of the core features of this library, I have compiled the main information: Aspect Description Core … Read more

When it comes to programming, many people fall into the “either-or” fallacy: thinking that Scratch is for “children” while C++ is for “serious programming.” However, few notice that these two seemingly disparate tools actually share the same “soul”—algorithmic logic.Today, we will break down a key question: Are Scratch and C++ “of the same origin” or … Read more
In the realm of programming, C++ stands out with its powerful performance and flexibility. However, within this language that pursues ultimate efficiency lies a seemingly contradictory yet profound wisdom—“laziness“ philosophy. This philosophy is not an excuse for idleness, but a well-considered design strategy that profoundly influences the evolution of modern software architecture and offers significant … Read more
