CPP Function Parameters

🎯 한 줄 통찰 (One-line insight)

Passing a string parameter directly (myFunction(string fname)) requires NO special array-declaration syntax the way C would (where a string parameter needs char name[]) — confirming that C++'s genuine string type flows naturally into function signatures too, letting a function accept and concatenate names as simply as it would numbers. [S1]

🧠 핵심 개념 (Core concepts)

• Parameter vs. argument — parameter is the variable name in the signature; argument is the actual value passed at the call site. [S1]
• String parameters work directly — void myFunction(string fname), no array declaration needed unlike C. [S1]
• Reused function logic across calls — the same function body runs once per call with different arguments. [S1]

📖 세부 내용 (Details)

• A string parameter reused across three calls: void myFunction(string fname) { cout << fname << " Refsnes\n"; } myFunction("Liam"); myFunction("Jenny"); myFunction("Anja"); — each call appends " Refsnes" to a different name. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

• string 매개변수에 배열 문법이 필요 없음: C에서는 문자열 매개변수를 char name[]으로 선언해야 했지만, C++에서는 string fname처럼 직접 선언 가능하다는 점이 확인됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 이름 뒤에 성(Refsnes)을 자동으로 붙여 출력하는 예제가 문자열 매개변수 활용의 대표 사례다. [S1]

💻 코드 패턴 (Code patterns)

A string parameter used directly, no array syntax needed (C++):

void myFunction(string fname) {
  cout << fname << " Refsnes\n";
}
int main() {
  myFunction("Liam");
  myFunction("Jenny");
  return 0;
}
