Today, I studied callback functions and recorded some of my thoughts based on articles from experts online. I will continue to write about the subsequent topics. What is a callback function? A callback function is a function that is called through a function pointer. If you pass the pointer (address) of a function as a … Read more
Author:PhyJack https://www.cnblogs.com/phyjack/p/18445368 Overview This article provides a detailed introduction to pointers of ordinary functions and member functions of classes in C/C++. It explains practical techniques for using function pointers as inputs to other functions, return values, and how typedef can enhance code readability, illustrated with C++ code examples. For member function pointers of classes, the … Read more
In C, a function pointer is a special type of pointer that can store the address of a function. With function pointers, we can flexibly call different functions, thereby enhancing the flexibility and scalability of the program. This article will introduce the basic definition of function pointers, how to use them, and some common application … Read more
Today, I will explain pointers. From basic to advanced, this article will combine practical applications to help you learn pointers while understanding what experts use pointers for!Long article warning! The entire text is about 5200 words, and this article is enough to learn pointers!Many people, like me when I first learned C language, are afraid … Read more
I remember when I first started working, a senior developer told me that if you are not familiar with longjmp and setjmp, you shouldn’t call yourself a C language expert. At that time, I was skeptical, but to advance my skills, I spent some time learning how to use longjmp and setjmp. Later, I realized … Read more
Function pointers are a powerful feature in the C programming language, allowing programs to pass, store, and dynamically call functions as data, providing great flexibility in code design. This article will systematically explain function pointers from their definition syntax, basic usage to advanced applications (callback mechanisms, state machines, plugin systems, object-oriented simulation), combining core insights … Read more
This article provides a detailed analysis of declarations in the C language, progressing step by step to thoroughly resolve this challenging topic. It is highly recommended to bookmark it. Pre-Class Question? What does the following declaration mean? char *const *(*next)(); First, give your answer. The standard answer will gradually become clear throughout this article’s step-by-step … Read more
01Hook FunctionsHook functions are predefined hooks in a program that allow you to attach or register a hook function when needed, making it available for the target.If there are no hooks, you can also obtain function pointers to encapsulate functions, but this can only be attached before or after the function runs, not during its … Read more
1 Object-Oriented C Object-oriented languages are closer to human thinking patterns, significantly reducing code complexity while enhancing code readability and maintainability. Traditional C code can also be designed to be readable, maintainable, and of lower complexity. This article will illustrate this with a practical example. 2 Basic Knowledge 2.1 Structures In addition to providing basic … Read more
