CSharp Operators

🎯 한 줄 통찰 (One-line insight)

The seven arithmetic operators (+ - * / % ++ --) and their exact symbols/semantics are unchanged across C, C++, and now C# — this chapter is the second (after Comments) where "how is C# different" has no answer at all, reinforcing that C#'s syntactic closeness to the C family is strongest at the expression-operator level and only diverges once whole-program structure (mandatory classes) or memory model (managed runtime) enters the picture. [S1]

🧠 핵심 개념 (Core concepts)

• + — addition; also usable to chain sums across variables (sum2 = sum1 + 250;). [S1]
• - — subtraction. [S1]
• * — multiplication. [S1]
• / — division. [S1]
• % — modulus (division remainder). [S1]
• ++ — increment, increases a variable's value by 1. [S1]
• -- — decrement, decreases a variable's value by 1. [S1]

📖 세부 내용 (Details)

• Direct literal addition: int x = 100 + 50;. [S1]
• Chained variable addition: int sum1 = 100 + 50; int sum2 = sum1 + 250; int sum3 = sum2 + sum2; → 150, 400, 800. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

• C/C++와 완전히 동일한 산술 연산자 집합: + - * / % ++ -- 7개 연산자의 기호와 의미가 C/C++와 전혀 차이가 없다는 점이 이번 챕터에서 확인됨 — Comments 챕터에 이은 두 번째 "완전 동일" 사례. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 여러 변수를 연쇄적으로 더해 누적 합을 만드는 예제가 원문에서 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Chained arithmetic across variables (C#):

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