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):
int sum1 = 100 + 50; // 150 (100 + 50)
int sum2 = sum1 + 250; // 400 (150 + 250)
int sum3 = sum2 + sum2; // 800 (400 + 400)
