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
When writing C++ programs, we sometimes need to verify whether certain conditions are met, such as whether the array size is acceptable or whether template parameters are valid. If these issues are discovered at runtime, they can cause the program to crash unexpectedly. Static assertions (static_assert) are a compile-time tool provided by C++, which can … 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
Imagine you are ordering a cup of milk tea 🧋… “Boss, I want a cup of pearl milk tea!” “Do you want to adjust the sweetness and ice level?” “No, the default is fine!” This scene seems very familiar, right? In the programming world, C++ default parameters are like the “standard configuration” at a milk … Read more
1. The Emergence of the C++20 Module System 1. The Emergence of the C++20 Module System In the world of C++ programming, the traditional header file mechanism has long been a double-edged sword. On one hand, it provides some convenience for code organization and reuse; on the other hand, it brings many tricky problems that … Read more
Introduction: The Collision of C++ and Neural Networks In today’s programming world, C++ is like a low-key yet powerful “behind-the-scenes hero”, firmly dominating the field of high-performance computing. From the stunningly realistic graphics rendering in game development to precise handling of complex data in scientific computing, C++ builds efficient systems through its near-ultimate control over … Read more
Hello, friends! I’m Hui Mei 😊. Today, we’re going to discuss rvalue references and move semantics in C++. These are important features introduced in C++11, specifically designed to enhance program performance, especially when your code requires a lot of object copying. These two techniques become particularly crucial! You might be wondering: “Rvalue references? Sounds complicated… … Read more
Introduction: The Wonderful Collision of C++ and Neural Networks Today, the wave of AI is sweeping across the globe, from facial recognition payments to intelligent voice assistants, from precise medical imaging diagnosis to self-driving cars, the presence of neural networks is ubiquitous. It has become the core engine driving these innovative applications. In the realm … Read more
C++’s polymorphism is one of its most powerful features and a cornerstone of object-oriented programming. Through polymorphism, we can call derived class functions using base class pointers or references without needing to know the specific derived class type. So, how is this “magic” achieved? The answer lies in the virtual table (vtable)! It is the … Read more
