Structural Design Patterns in Modern C++ - Implementing Sharing for String Objects.

The video tutorial explains the concept of shared strings, which allows multiple string instances to share the same data, reducing memory usage. It details the implementation using C++17 features, such as unordered maps and inline static variables. The tutorial demonstrates the practical application of shared strings, highlighting the benefits of reduced copying. It introduces the copy-on-write mechanism, where resources are copied only when necessary. Finally, the video discusses the bridge pattern and handle-body idiom, emphasizing the one-to-one mapping between abstraction and implementation.
