In C programming, memory management is a crucial topic. Effective memory usage not only improves program performance but also avoids potential memory leaks and crashes. This article will introduce several methods to reduce memory usage in C programs, demonstrated with code examples. 1. Use Appropriate Data Types Choosing the right data type is the first … Read more
Scan the code to follow Chip Dynamics and say goodbye to “chip” congestion! Search WeChatChip Dynamics Imagine opening a Russian nesting doll, and inside is an even smaller doll, and then another… The concept of a pointer to a pointer in C language (double pointer) is like this nesting doll game! Each layer of pointer … Read more
In software development, performance analysis is a crucial aspect. It helps us identify bottlenecks in the program, allowing us to optimize code and improve execution efficiency. This article will introduce some commonly used performance analysis tools and methods, along with example code demonstrations. 1. The Importance of Performance Analysis In C programming, performance issues can … 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

01 (Common Mistake) The basic unit of a C program is a function (True/False) Answer: True Explanation: The basic unit of a C program is a function. C is a structured programming language, and a C program consists of one or more functions. Every C program must include the main() function as the entry point, … Read more
Recently, I came across a very interesting term “callback hell”, which refers to the endless nesting of callback functions that ultimately leads to stack overflow and deadlock. The manifestation of this is multiple layers of nested function pointer callbacks, resulting in poor code readability and maintenance difficulties.Below is a simple example simulating asynchronous file reading … Read more
In data structures, linked lists are a very important linear data structure. Unlike arrays, linked lists do not require a predefined size and can dynamically increase or decrease in elements. In this article, we will detail how to create and operate on singly linked lists in C. What is a Singly Linked List? A singly … Read more
In network programming, UDP (User Datagram Protocol) is a connectionless transport layer protocol. Unlike TCP, UDP does not guarantee the order of packet delivery and does not provide a retransmission mechanism, making it suitable for scenarios that require high speed but low reliability, such as video streaming and online gaming. This article will introduce how … Read more
