# [[CPP Strings]]

## 🎯 한 줄 통찰 (One-line insight)
Unlike C, where storing multi-word text requires manually managing a `char` array and worrying about the null terminator, C++'s `string` type stores spaces and punctuation transparently ("Hello and welcome!" works with zero special handling) — proving that the earlier Data Types chapter's promise (string "behaves like" a built-in type) holds even for the exact scenario C explicitly warned about. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`string`** — stores a sequence of characters (text), double-quoted; requires `#include <string>`. [S1]
- **Multi-word support with zero friction** — spaces and punctuation are stored and printed transparently, no escape handling or array sizing needed. [S1]

## 📖 세부 내용 (Details)
- Basic string with the required include: `#include <string> string greeting = "Hello"; cout << greeting;`. [S1]
- Multi-word string with spaces and punctuation: `string greeting = "Hello and welcome!"; cout << greeting;`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **C의 다중 단어 문자열 문제가 C++에는 없음**: C에서는 char 배열의 크기와 널 종료 문자를 신경 써야 했지만, C++ string은 공백과 구두점을 포함한 여러 단어를 아무 특별 처리 없이 그대로 저장/출력한다는 점이 확인됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — <string> 헤더 포함이 문자열을 다루는 모든 C++ 프로그램의 실전 필수 전제 조건이다. [S1]

## 💻 코드 패턴 (Code patterns)
A multi-word string with spaces and punctuation, stored and printed transparently (C++):
```cpp
#include <string>
string greeting = "Hello and welcome!";
cout << greeting;
```
