Understanding the Foundation of libc++ STL Source Code — SFINAE

In my opinion, when learning system programming languages (C++/Rust/C), one should not be impatient; it is essential to build a solid foundation to progress further. Before we delve into the libc++ STL source code, we need to understand a concept called SFINAE. SFINAE stands for Substitution Failure Is Not An Error, which translates to ‘substitution … Read more

C++ Rule of Zero: The Evolution from Rule of Three to Rule of Zero

Resource Management and Ownership In C++, the destructor of an object with automatic storage duration is called when its scope ends. This feature is often used to implement the RAII (Resource Acquisition Is Initialization) pattern to automatically handle resource cleanup. The core of RAII is the concept of resource ownership: an object responsible for cleaning … Read more

Introduction to C++: Inheritance and Polymorphism

Inheritance One of the important features of C++ is code reuse. Through the inheritance mechanism, new data types can be defined using existing data types. The new data type not only has the members of the old class but also has new members. Class B inherits from class A, also known as deriving class B … Read more

In-Depth Explanation of the Composite Pattern in C++ Design Patterns

The Composite Pattern is a structural design pattern that allows you to compose objects into tree structures to represent part-whole hierarchies. This pattern enables clients to treat individual objects and compositions of objects uniformly, without needing to differentiate between handling a single object or an entire object tree. Core Roles of the Composite Pattern Abstract … Read more
