Hello everyone, nice to see you again! Continuing from our last session, we have set up a warm and comfortable environment for C++ development. Today, I will guide you to understand the relationship between C and C++, reviving our long-dormant memories of C! Differences Between C++ and C First and foremost, the simplest difference is … Read more
Embedded development sounds impressive, but it’s not that special. It’s just using C++ on small devices, like smartwatches or home appliance controllers. Today, we’ll talk about how to use C++ to handle the control logic of these little gadgets. Don’t worry, it’s quite simple! 1 Let’s Talk About the Characteristics of Embedded Development Embedded development … Read more
Development and Optimization of Embedded Systems Hey, C++ friends, today Hui Xiaoqin wants to talk to you about the application of C++ in the Internet of Things (IoT), especially in the development and optimization of embedded systems. The IoT is like a giant network connecting various devices and sensors, and embedded systems are the brains … Read more
Writing embedded systems is indeed an interesting task. Unlike regular application development, we have to deal directly with the hardware and also worry about memory usage and real-time performance. As a veteran in embedded systems for over a decade, I find that developing embedded systems with C++ is quite cool. It allows us to utilize … Read more
Introduction I have been researching IO for a long time and have been unable to connect bio and block device drivers. I only knew that bio is passed to the block device driver through the IO scheduling algorithm, but I never fully understood how this happens or where the IO scheduling algorithm plays its role. … Read more
Set Script Home as “Starred⭐” Receive article updates in real-time Source: Rust Development Notes (ID: gh_8009fefbaa0f) In the current programming world, Python is widely accepted by developers, and it goes without saying. Its concise and powerful features allow developers to quickly write efficient and readable code. However, as software projects become increasingly complex, code efficiency … Read more
C++ exception handling is one of the important features for improving program robustness and maintainability. In C++, resource management is closely related to exception handling, especially in ensuring that resources are correctly released in the event of an exception. In this regard, RAII (Resource Acquisition Is Initialization) is a very important design pattern that uses … 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
Question: When performing pointer + operations, how much does the address actually offset? This question is essentially a fundamental issue in C programming. However, I have stumbled on this as well, so I write this as a lesson and a reminder for everyone. We know that the essence of a pointer is a memory address, … Read more
