Inheritance and Derivation: The Core Mechanism of Object-Oriented Programming in C++

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

The C++ Ecosystem Dilemma: A Decade of Struggles in Building and Dependency Management

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

Efficient C++ Practices: A Library Everyone Should Pay Attention To

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
