Pointer Operations Pointer operations give it powerful functionality. In addition to the dereference operation (*) and the address-of operation (&), pointers also support some arithmetic operations. For example, pointers can perform addition and subtraction, but it is important to note that pointer addition and subtraction are not simple numerical addition or subtraction; they are based … Read more
C++ References: Differences from Pointers, Use Cases, and Advantages In C++ programming, references and pointers are two very important concepts. Both can be used to manipulate data in memory, but their characteristics and usage differ significantly. This article will detail references in C++, including the differences from pointers, common use cases, and their advantages. What … Read more
1. Common Yet Easily Ignored Bad Code Smells 1. Inconsistent Code Style: In the same project, some code uses C-style functions and syntax, while another part heavily adopts C++ object-oriented features. This mixed style can make the code look chaotic. For example, in one file, there is a mix of data manipulation using structures and … Read more
At that time, I was preparing to develop a new desktop application. Can Rust really save me from being replaced by AI? Can I become the legendary “10x engineer”? As a web developer, I feel a bit uneasy about whether I can be considered a “real developer.” Moreover, since this is a desktop application, I … Read more
Introduction Memory management has always been one of the core challenges in programming language design. In many languages, developers need to manage memory manually, which can easily lead to issues such as memory leaks and dangling pointers. In contrast, Rust provides a completely new approach to memory management through its unique ownership, borrowing, and lifetimes … 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
Custom Commands The following statement is written in ~/.gdbinit to define a custom command lmem. This command requires one parameter, which is a memory address that serves as the head of a linked list. The structure of the linked list is BlockLink_t. The function of this command is to traverse the linked list and print … Read more
