1. Introduction 1.1 Importance of Memory Management In computer science, memory management is a crucial part of operating systems. It is responsible for managing the main memory (primary storage) of the computer, which is the storage space directly accessible by the CPU, including physical memory and all available virtual memory. The main tasks of memory … Read more
Click the topPublic Account to follow us~ In software development, design patterns are tools that help make code structure clearer, more maintainable, and extensible. The MVC (Model-View-Controller) pattern is one of the classic design patterns widely used in graphical user interface (GUI) applications. Qt, as a powerful cross-platform development framework, also adopts the MVC pattern … Read more
01 Use Structures to Store Common Variables in AdvanceWhen writing preprocessing and postprocessing functions, certain variables, such as the shape of the model input tensor and count, are often used multiple times. If these values are recalculated in each processing function, it will increase the computational load during deployment. In such cases, consider using a … Read more
ezc3d: A Powerful Tool for Biomechanical Data Processing In biomechanical research, data storage and processing are crucial steps. The C3D file format, as a widely used standard, is specifically designed for storing biomechanical data, such as three-dimensional motion capture data and force platform data. However, for a long time, the biomechanics field has lacked a … Read more
In multithreaded programming, there are two issues to pay attention to: one is data races, and the other is memory execution order. What is a data race? First, let’s look at what a data race is and what problems it can cause. #include <iostream> #include <thread> int counter = 0; void increment() { for (int … Read more
In C++ programming, a macro is a text replacement tool processed by the preprocessor, implemented through the <span>#define</span> directive. While macros can be very useful in certain scenarios, they are also controversial due to their potential side effects. This article will cover the basic syntax, common uses, drawbacks, and modern alternatives to help developers use … Read more
Introduction:In C++ development, have you ever encountered memory leaks caused by local objects not being destructed properly? Why do the destructors of certain objects not execute when exiting the program using <span><span>exit()</span></span>? This article delves into the core mechanisms of program exit through code examples, helping you avoid the pitfalls of resource management! 1. A … Read more
