Memory Leak Detection Methods in C++ In C++ programming, memory management is an important topic. Incorrect memory allocation and deallocation can lead to memory leaks, which affect the performance and stability of the program. This article will introduce several methods for detecting memory leaks in C++ programs and provide corresponding code examples. What is a … 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
Source | AuthorizedTransferred from Xuanyuan’s Programming Universe (ID: xuanyuancoding)Author | Xuanyuan Wind One weekend, someone in my reverse learning group from scratch threw out a C language-related question: First, think about what this code will output after running? I encountered this question a few years ago in a Huawei interview. The code is very short; … Read more
Click the aboveblue text to follow us Memory leaks are a serious issue in embedded system development, especially in resource-constrained environments. Unlike desktop applications, embedded systems often have strict memory limitations, where even small memory leaks can quickly lead to system crashes or functional anomalies. A memory leak refers to a situation where a program … Read more
Book Giveaway at the End 01 A Classic C++ Interview Question Is it difficult for beginners to pass interviews at major companies? Let’s first look at a classic C++ interview question. “Can you explain the principles and uses of smart pointers?” If students have memorized the strategies, they can probably say that smart pointers are … Read more
C++ Embedded Development: Achieving Efficient Programs on Resource-Constrained Devices Hey, friends, I am Xiaohui. Today, let’s talk about how to utilize some features of C++ in embedded development to ensure programs run efficiently on resource-constrained devices. Embedded devices have limited memory and weak processors, which means we need to make every resource count. Don’t worry, … Read more
Introduction In Rust, smart pointers are structures that encapsulate pointers, responsible for managing memory and automatically reclaiming resources. Rust’s memory management is centered around ownership, but in some cases, programmers may need more flexibility, especially when dealing with shared ownership and mutability. At this point, Rust offers several smart pointers, the most commonly used being … Read more
Introduction In Rust, memory management is a very important task. Rust helps developers avoid many common memory issues through mechanisms such as ownership, borrowing, and lifetimes. However, Rust also provides some smart pointers for handling heap-allocated memory, which not only simplify memory management but also give us more flexibility. This article will detail several smart … Read more
In the world of C++ programming, resource management has always been a headache, especially when dealing with memory, file handles, and other system resources. Today, I want to explore a very important concept with you—RAII (Resource Acquisition Is Initialization). Through this article, you will understand how RAII helps us manage resources effectively, avoiding common memory … Read more
In C++, forgetting to release dynamically allocated memory is a common pitfall for beginners. To address this issue, smart pointers have emerged. The smart pointer std::shared_ptr allows multiple pointers to share the same memory and manages its lifecycle through reference counting, which is very convenient. However, std::shared_ptr is not infallible; it has a fatal flaw: … Read more
