# [[C Operators]]

## 🎯 한 줄 통찰 (One-line insight)
The chapter's own chained example — `sum1 = 100 + 50; sum2 = sum1 + 250; sum3 = sum2 + sum2;` — demonstrates that `+` works identically whether combining two literals, a variable and a literal, or two variables, establishing early that C operators operate on VALUES regardless of whether those values come from literals or variable lookups. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Operator** — performs an operation on variables and/or values. [S1]
- **Five operator categories** — Arithmetic, Assignment, Comparison, Logical, and Bitwise (marked "advanced"). [S1]
- **Uniform operand handling** — the same operator (e.g. `+`) 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)
- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이 챕터가 제시하는 5개 연산자 분류가 이후 각 챕터(산술/대입/비교/논리/비트) 학습의 로드맵 역할을 한다. [S1]

## 💻 코드 패턴 (Code patterns)
The + operator working uniformly across literals, a variable+literal, and variable+variable (C):
```c
int sum1 = 100 + 50;        // 150 (100 + 50)
int sum2 = sum1 + 250;      // 400 (150 + 250)
int sum3 = sum2 + sum2;     // 800 (400 + 400)
```
