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
C++ memory management is a core topic in programming, involving complex concepts such as pointers, dynamic memory allocation, memory leaks, and memory fragmentation. C++ provides the ability to manipulate memory directly, which brings flexibility but also comes with higher complexity and the risk of errors. To aid in understanding C++ memory management, we will explore … Read more
Hi, friends! Today we are going to talk about a very important tool in C++—Smart Pointers. If you have previously written dynamic memory management code in C++, you may be familiar with new and delete. But have you ever fallen into the pit of memory leaks because you forgot to call delete? Or crashed your … Read more
In C++, resource management is a very important topic, especially when it comes to managing system resources such as memory, files, and network connections. C++ provides powerful tools and features to help programmers manage these resources efficiently and safely, with one of the key techniques being the application of smart pointers. In this article, we … Read more
C++ and Embedded Systems: Core Technologies for IoT Device Development Hello everyone, I’m Xiao Shao. Today, let’s talk about a very practical knowledge point in C++—smart pointers. In the world of C++, smart pointers are like our capable assistants in managing memory. They help us automatically manage memory, avoid memory leaks, and make our code … Read more
Hello everyone! Today we will explore a very important C++ concept—smart pointers. As a beginner, you may encounter memory management issues during your learning process. Smart pointers were created to solve these problems; they help us manage memory better and avoid those pesky memory leaks. Next, I will guide you step by step to understand … Read more
