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;
