# [[CPP Intro]]

## 🎯 한 줄 통찰 (One-line insight)
The source reduces the entire C vs C++ distinction to ONE sentence — "C++ supports classes and objects, while C does not" — meaning everything else commonly associated with C++ (templates, STL, inheritance, polymorphism) is really downstream consequence of that single foundational addition, not a separate list of unrelated features layered onto C. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Origin** — created by Bjarne Stroustrup as an extension of C. [S1]
- **Major version history** — updated 5 times: C++11, C++14, C++17, C++20, C++23 (2011/2014/2017/2020/2023). [S1]
- **Cross-platform, high-performance** — used in operating systems, GUIs, and embedded systems. [S1]
- **Object-oriented** — gives clear program structure and enables code reuse, lowering development cost. [S1]
- **The single core C vs C++ difference** — C++ supports classes and objects; C does not. Nearly identical syntax otherwise. [S1]
- **Proximity to C/C#/Java** — makes switching between these languages and C++ relatively easy. [S1]

## 📖 세부 내용 (Details)
- C++'s five major standard revisions listed explicitly: C++11 (2011), C++14 (2014), C++17 (2017), C++20 (2020), C++23 (2023). [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 운영체제, GUI, 임베디드 시스템이 원문에서 언급된 C++의 대표적 실전 활용 분야다. [S1]

## 💻 코드 패턴 (Code patterns)
None — this is a conceptual overview page with no standalone code example.

## ✅ 검증 상태 및 신뢰도
