Implementing Linked List Data Structure in C++ A linked list is a type of linear data structure consisting of a series of nodes. Each node contains two parts: a data field and a pointer to the next node. Unlike arrays, linked lists do not require contiguous memory space, making them more efficient for insertion and … Read more
Memory Management and Optimization in C++ C++ is a powerful and flexible programming language, but it also presents challenges in memory management for programmers. This article will introduce the basic concepts of memory management in C++ and some optimization techniques to help beginners better understand and utilize memory. 1. Basics of Memory Management In C++, … Read more
Hello everyone, I am Bug Jun~ In most people’s impression, writing a technical book is just about organizing what you know. However, when the subject is the Linux kernel, it becomes like performing ballet on a tightrope — one of the most complex open-source software in the world, a giant system composed of 28 million … Read more
1. Character Arrays and Strings #include <stdio.h> int main(int argc, const char *argv[]) { // "abcde" // Multiple characters can be stored in a character array. char s1[5] = {'a', 'b', 'c', 'd', 'e'}; int i = 0; for (i = 0; i < 5; i++) { printf("%c", s1[i]); } printf("\n"); // "www.hqyj.com" // A … Read more
In the C language, a union is a special custom data type that allows different types of data to be stored in the same memory location. Unlike a structure, all members of a union share the same memory segment, which means that at any given time, a union can only store the value of one … Read more
Company coding standards prohibit the use of unsafe functions and require the use of custom safe functions developed internally. In C language, some functions are not absolutely safe, such as memcpy which may have overlapping memory regions; strcpy, gets, and sprintf do not check the size of the target buffer; and scanf series (which do … Read more
“From today onwards, study hard and make progress every day” Repetition is the best method for memory; spend one minute each day to remember the basics of C language. 1. Basic Understanding of C Language 1.Features of C Language • Procedural/Structured Language • Efficiency (close to hardware) • Strong portability (standard library specifications) • Direct … Read more
1. Why is Memory Management a Must for Python Engineers? At the 2025 Python Developers Summit, memory-related issues accounted for 73%, with memory leak cases making up as much as 58%. This article will guide you through the underlying principles and industrial-grade solutions of Python memory management through three practical scenarios: memory leak detection, object … Read more
In the embedded field, embedded real-time operating systems are becoming increasingly widely used. Using an embedded real-time operating system (RTOS) can more reasonably and effectively utilize CPU resources, simplify application software design, shorten system development time, and better ensure the system’s real-time performance and reliability. FreeRTOS is a mini real-time operating system kernel. As a … Read more
In the field of computer science, the concept of a stack is likely familiar to many. The familiarity and understanding of stacks primarily stem from two aspects. One aspect is that a stack is a type of data structure characterized by the Last In, First Out (LIFO) principle. The other aspect is that a stack … Read more
