Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

CPP Inheritance

🎯 한 줄 통찰 (One-line insight)

The Car class never declares a brand attribute or a honk() method of its own — it inherits BOTH directly from Vehicle via the single : public Vehicle syntax, and myCar.honk() works exactly as if honk() had been written inside Car itself, meaning inheritance in C++ isn't a reference or delegation mechanism but a literal MERGING of the parent's members into the child, accessible with zero extra syntax at the call site. [S1]

🧠 핵심 개념 (Core concepts)

Inheritance — one class (derived/child) reuses attributes and methods from another (base/parent), avoiding duplication. [S1]
: public BaseClass — the syntax for inheriting; placed after the derived class's name. [S1]
Zero-syntax access to inherited members — a child object calls inherited methods and reads inherited attributes exactly like its own, with no special prefix. [S1]
Why inherit — code reusability — reuse an existing class's attributes/methods when creating a new one. [S1]

📖 세부 내용 (Details)

A child class inheriting an attribute and method from its parent: class Vehicle { public: string brand = "Ford"; void honk() { cout << "Tuut, tuut! \n"; } }; class Car: public Vehicle { public: string model = "Mustang"; }; Car myCar; myCar.honk(); // inherited from Vehicle cout << myCar.brand + " " + myCar.model; // brand inherited, model is Car's own. [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 — Vehicle의 brand와 honk()를 Car가 그대로 물려받는 예제가 상속을 통한 코드 재사용의 대표 실전 활용이다. [S1]

💻 코드 패턴 (Code patterns)

A child class inheriting an attribute and method from its parent with zero extra syntax (C++):

class Vehicle { // Base class
public:
  string brand = "Ford";
  void honk() { cout << "Tuut, tuut! \n"; }
};
class Car: public Vehicle { // Derived class
public:
  string model = "Mustang";
};
int main() {
  Car myCar;
  myCar.honk(); // inherited method, works directly
  cout << myCar.brand + " " + myCar.model;
  return 0;
}
