# [[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++):
|
|
```cpp
|
|
cout << "Hello World!";
|
|
cout << "Have a good day!";
|
|
return 0;
|
|
```

## ✅ 검증 상태 및 신뢰도
|
|
- **상태:** draft
|
|
- **검증 단계:** conceptual
|
|
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
|
|
- **신뢰 점수:** 0.83
|
|
- **중복 검사 결과:** 신규 생성 (New discovery)
|
|
|
|
## 🔗 지식 그래프 (Knowledge Graph)
|
|
- **상위/루트:** [[C++ Tutorial]]
|
|
- **관련 개념:** [[CPP Syntax]], [[CPP Comments]]
|
|
- **참조 맥락:** 명령문과 세미콜론 규칙 — 주석(Comments) 챕터로 이어짐.
