# [[C++ OOP]]

## 🎯 한 줄 통찰 (One-line insight)
The single-sentence distinction the source draws between procedural and object-oriented programming is organizational, not functional — procedural code is "organized around FUNCTIONS," OOP code is "organized around OBJECTS" that BUNDLE data and functions together — meaning the shift to OOP throughout this section of the tutorial isn't introducing new capabilities C++ lacked before, but reorganizing the SAME capabilities (variables, functions) around a different unit of grouping. [S1]

## 🧠 핵심 개념 (Core concepts)
- **OOP (Object-Oriented Programming)** — organizing code around "objects" that hold both data and functions operating on that data. [S1]
- **Class vs. object** — a class defines what an object should look like (a template); an object is created FROM a class and inherits its variables/functions. [S1]
- **DRY principle** — "Don't Repeat Yourself"; move repeated code into functions or classes and reuse it. [S1]
- **OOP advantages** — clearer program structure, easier maintenance/reuse/debugging, DRY-friendly, enables building full reusable applications faster. [S1]
- **Procedural vs. OOP** — procedural organizes code around FUNCTIONS operating on data; OOP organizes code around OBJECTS that contain both data and functions together. [S1]

## 📖 세부 내용 (Details)
- The Class → Objects mapping example: Fruit class → Apple/Banana/Mango objects; Car class → Volvo/Audi/Toyota objects. [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 — 이 챕터의 클래스-객체 개념 개관이 다음 챕터(Classes and Objects)의 실전 코드로 바로 이어진다. [S1]

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