Antigravity Agent 9a135bd19d docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동
최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치.
콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서
전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한
업데이트0615/무제 3.canvas 뿐).

CPP Statements

🎯 한 줄 통찰 (One-line insight)

Just as in C, a missing semicolon produces an error message pointing to the NEXT statement rather than the actual offending line (error: expected ';' before 'return') — the identical error-location quirk from the C tutorial carries over unchanged to C++, confirming both languages share the same underlying parser behavior for this specific mistake. [S1]

🧠 핵심 개념 (Core concepts)

  • Statement — one instruction executed by the compiler; the basic building block of a C++ program. [S1]
  • Mandatory semicolon termination — every statement must end with ;; omitting it causes a compile error. [S1]
  • Sequential execution — multiple statements execute strictly top-to-bottom, in written order. [S1]

📖 세부 내용 (Details)

  • Missing-semicolon error: cout << "Hello World!" (no ;) → error: expected ';' before 'return'. [S1]
  • Sequential multi-statement execution: cout << "Hello World!"; cout << "Have a good day!"; return 0; — runs top to bottom. [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 — C의 동일한 세미콜론 규칙과 에러 위치 특성이 그대로 이어진다는 점이 C 학습자가 C++로 전환할 때 유리한 지점이다. [S1]

💻 코드 패턴 (Code patterns)

Three statements executing sequentially in source order (C++):

cout << "Hello World!";
cout << "Have a good day!";
return 0;
