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 Boolean Examples

🎯 한 줄 통찰 (One-line insight)

This chapter explicitly reframes the entire preceding Comparison/Boolean material as mere PREPARATION for if...else — printing a raw 1 or 0 (as done in every earlier example) is functionally correct but not directly useful to an end user, and the source's own upgrade (wrapping the same comparison in if (myAge >= votingAge) {...} else {...}) shows that booleans are the evaluated CONDITION inside control flow, not typically an end product to display as-is. [S1]

🧠 핵심 개념 (Core concepts)

Comparison as raw output — printing a comparison directly (printf("%d", myAge >= votingAge);) shows 1 or 0, technically correct but not user-friendly. [S1]
Comparison as an if condition — the SAME comparison expression, placed inside if (...), drives which branch of code executes, producing human-readable output instead of a raw 1/0. [S1]
Booleans as the foundation of conditions — the chapter explicitly states booleans "are the basis for all comparisons and conditions," directly foreshadowing the next chapter's Conditions/if-else content. [S1]

📖 세부 내용 (Details)

Raw comparison output: int myAge = 25; int votingAge = 18; printf("%d", myAge >= votingAge); // Returns 1 (true). [S1]
The same logic upgraded into an if...else: if (myAge >= votingAge) { printf("Old enough to vote!"); } else { printf("Not old enough to vote."); }. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).

🛠️ 적용 사례 (Applied in summary)

투표 가능 연령(18세) 확인 로직을 raw 1/0 출력에서 if...else로 업그레이드하는 것이 이 챕터가 직접 보여주는 실전 활용 사례이자, 다음 챕터(Conditions)로의 전환점이다. [S1]

💻 코드 패턴 (Code patterns)

The same boolean comparison used inside an if...else for human-readable output (C):

int myAge = 25;
int votingAge = 18;
if (myAge >= votingAge) {
  printf("Old enough to vote!");
} else {
  printf("Not old enough to vote.");
}
