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.

C++ C-Style Strings

🎯 한 줄 통찰 (One-line insight)

C++ never removed C's original char-array string technique — it kept it fully supported alongside the modern string type specifically because it grants access to C standard library functions, meaning a C++ program can legally contain BOTH string styles simultaneously, and choosing C-style strings today is a deliberate interoperability decision, not a leftover habit from not knowing about string. [S1]

🧠 핵심 개념 (Core concepts)

  • C-style string — a char array (e.g. char greeting2[] = "Hello";), the original C technique, inherited and still supported in C++. [S1]
  • Origin — named after C, which lacks a native string type and represents text as character arrays. [S1]
  • Why it persists in C++ — grants access to functions from the C standard library (CString functions). [S1]
  • Modern recommendation — the standard string type is more convenient for everyday use; C-style strings are a deliberate choice for specific interoperability needs. [S1]

📖 세부 내용 (Details)

  • Both string styles side by side: string greeting1 = "Hello"; // Regular String char greeting2[] = "Hello"; // C-Style String (an array of characters). [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 — C 표준 라이브러리 함수에 접근해야 하는 상황이 C 스타일 문자열을 계속 사용하는 실전 이유로 원문에 직접 제시됨. [S1]

💻 코드 패턴 (Code patterns)

The same text represented as a regular C++ string versus a C-style character array (C++):

string greeting1 = "Hello";  // Regular String
char greeting2[] = "Hello";  // C-Style String (an array of characters)
