# [[CPP Pass Array to a Function]]

## 🎯 한 줄 통찰 (One-line insight)
Calling `myFunction(myNumbers)` only needs the ARRAY NAME, but the function's own parameter must still spell out the full declaration (`int myNumbers[5]`) — the same asymmetry from C's identical chapter, confirming this array-name-is-a-pointer behavior carries over from C to C++ completely unmodified. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Passing arrays** — call site uses just the array name; the function signature needs the full array declaration. [S1]
- **Same asymmetry as C** — bare name at the call site, full type+size at the parameter declaration. [S1]

## 📖 세부 내용 (Details)
- Passing and looping through an array parameter: `void myFunction(int myNumbers[5]) { for (int i = 0; i < 5; i++) { cout << myNumbers[i] << "\n"; } } int myNumbers[5] = {10,20,30,40,50}; myFunction(myNumbers);`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources). C 챕터와 동일한 배열-함수 매개변수 관계가 확인됨.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 숫자 배열을 함수에 전달해 순회 출력하는 패턴이 배열-함수 결합의 기본 실전 활용이다. [S1]

## 💻 코드 패턴 (Code patterns)
Passing an array to a function using just its name at the call site (C++):
```cpp
void myFunction(int myNumbers[5]) {
  for (int i = 0; i < 5; i++) {
    cout << myNumbers[i] << "\n";
  }
}
int main() {
  int myNumbers[5] = {10, 20, 30, 40, 50};
  myFunction(myNumbers);
  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 Function RealLife]], [[CPP Function Reference]], [[C Functions Parameters]]
- **참조 맥락:** 배열을 함수로 전달 — 참조로 전달(Function Reference) 챕터로 이어짐.
