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++):

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