The “C++ Basics” series of blogs serves as a reference to the book “C++ Primer (5th Edition)” (C++11 Standard), which includes my own study notes. 1. Type Aliases Type aliases are names that serve as synonyms for certain types. There are many benefits to using type aliases; they simplify complex type names, making them clearer … Read more
Why Do We Need Callback Functions? In traditional synchronous programming, we directly call functions and wait for their return results. This pattern is simple and intuitive, but when faced with time-consuming operations (such as I/O operations, network requests, etc.), the thread gets blocked, leading to low resource utilization. Callback functions are key to solving the … Read more
Inheritance and Derivation: The Core Mechanism of Object-Oriented Programming in C++ In object-oriented programming (OOP), inheritance is an important concept that allows us to create a class (subclass) that inherits properties and methods from another class (superclass). This approach enables code reusability and helps build more complex and feature-rich programs. What is Inheritance? In C++, … Read more
1Building Systems:The Migration Costs of the Warring States Period Fragmentation of Multiple Tools CMake/Bazel/Meson are in a three-way standoff: Syntax differences require relearning configuration logic for cross-project collaboration (e.g., CMake’s <span>target_link_libraries</span> conflicts with Bazel’s <span>deps</span> rule). Historical baggage hampers modernization: Legacy projects depend on Autotools-generated <span>configure</span> scripts, which have poor compatibility with modern IDEs (like … Read more

Hello everyone, I am Hai Di! In C++ development, string formatting is a frequent and easily overlooked requirement. Traditional methods such as <span>sprintf</span> pose risks of buffer overflow, while <span>iostream</span> has poor performance and cumbersome syntax. The fmt library, with its three main features of type safety, zero-cost abstraction, and minimal syntax, has become the … Read more
