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
