# [[CPP Operators]]
## 🎯 한 줄 통찰 (One-line insight)
C++ organizes operators into the SAME five categories as C (Arithmetic, Assignment, Comparison, Logical, Bitwise) — but unlike C's equivalent chapter, which explicitly labeled Bitwise as "advanced," C++'s overview lists it as an ordinary fifth category with no such qualifier, suggesting the tutorial treats bitwise operations as standard-tier knowledge rather than a specially-flagged advanced topic. [S1]
## 🧠 핵심 개념 (Core concepts)
- **Operator** — performs an operation on variables and/or values. [S1]
- **Five operator categories** — Arithmetic, Assignment, Comparison, Logical, Bitwise. [S1]
- **Uniform operand handling** — the same operator works on literal-literal, variable-literal, and variable-variable combinations identically. [S1]
## 📖 세부 내용 (Details)
- Chained addition using literals and variables interchangeably: `int sum1 = 100 + 50; int sum2 = sum1 + 250; int sum3 = sum2 + sum2;` — evaluates to 150, 400, 800. [S1]
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **비트 연산자가 "고급"으로 별도 표시되지 않음**: C 튜토리얼은 비트 연산자를 명시적으로 "advanced"라고 표시했지만, C++ 튜토리얼의 이 개관 챕터에서는 그런 수식어 없이 다섯 번째 일반 카테고리로만 나열됨. [S1]
## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이 챕터가 제시하는 5개 연산자 분류가 이후 각 챕터 학습의 로드맵 역할을 한다. [S1]
## 💻 코드 패턴 (Code patterns)
The + operator working uniformly across literals, a variable+literal, and variable+variable (C++):
```cpp
int sum1 = 100 + 50; // 150 (100 + 50)
int sum2 = sum1 + 250; // 400 (150 + 250)
int sum3 = sum2 + sum2; // 800 (400 + 400)
```
## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
- **신뢰 점수:** 0.82
- **중복 검사 결과:** 신규 생성 (New discovery)
## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[C++ Tutorial]]
- **관련 개념:** [[CPP Data Types RealLife]], [[CPP Operators Arithmetic]]
- **참조 맥락:** 연산자 섹션 개관 — 산술 연산자(Operators Arithmetic) 챕터로 이어짐.
