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 Operators

🎯 한 줄 통찰 (One-line insight)

The chapter's own chained example — sum1 = 100 + 50; sum2 = sum1 + 250; sum3 = sum2 + sum2; — demonstrates that + works identically whether combining two literals, a variable and a literal, or two variables, establishing early that C operators operate on VALUES regardless of whether those values come from literals or variable lookups. [S1]

🧠 핵심 개념 (Core concepts)

  • Operator — performs an operation on variables and/or values. [S1]
  • Five operator categories — Arithmetic, Assignment, Comparison, Logical, and Bitwise (marked "advanced"). [S1]
  • Uniform operand handling — the same operator (e.g. +) works on literal-literal, variable-literal, and variable-variable combinations identically. [S1]

📖 세부 내용 (Details)

  • Chained addition using literals and variables interchangeably: int sum1 = 100 + 50; int sum2 = sum1 + 250; int sum3 = sum2 + sum2; — evaluates to 150, 400, 800. [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 챕터가 제시하는 5개 연산자 분류가 이후 각 챕터(산술/대입/비교/논리/비트) 학습의 로드맵 역할을 한다. [S1]

💻 코드 패턴 (Code patterns)

The + operator working uniformly across literals, a variable+literal, and variable+variable (C):

int sum1 = 100 + 50;        // 150 (100 + 50)
int sum2 = sum1 + 250;      // 400 (150 + 250)
int sum3 = sum2 + sum2;     // 800 (400 + 400)
