## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2512, "days_push": 868, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of C++11 demo code implementing all 23 classic GoF design patterns, accompanied by Chinese-language tutorial notes and blog posts. It is an educational resource for learning object-oriented design principles and design patterns in C++.

## Use cases
- learn design patterns in c++
- study singleton factory observer pattern examples
- prepare for c++ design pattern interview questions
- see uml class diagrams with matching code
- understand object-oriented design principles

## When to choose
- you want runnable C++11 examples for each GoF pattern
- you are preparing for design pattern interviews in C++
- you prefer tutorials paired with blog explanations

## When to avoid
- you need a production-ready pattern library to link into your project
- you need non-C++ languages
- you need a maintained, licensed codebase for commercial use

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: tutorials, programming-languages, developer-tools
- platform: cpp, windows, cross-platform
- tags: design-patterns, cpp11, educational, uml, object-oriented-design, demo-code, linux
