CSharp Comparison Operators

🎯 한 줄 통찰 (One-line insight)

C#'s comparison operators return a genuine bool value (True/False), not C's convention of 1/0 integers standing in for truth — this is a direct, visible consequence of the Data Types chapter's earlier finding that bool is a real first-class type in C# (unlike classic C, where comparisons are just int expressions), so Console.WriteLine(x > y); prints the WORD "True", something a raw C comparison expression could never do without an explicit ? "true" : "false" ternary. [S1]

🧠 핵심 개념 (Core concepts)

• == — equal to. [S1]
• != — not equal. [S1]
• > / < — greater than / less than. [S1]
• >= / <= — greater than or equal to / less than or equal to. [S1]
• Return type is bool — every comparison evaluates to a true bool value (True or False), not an integer. [S1]
• Purpose — enables decision-making in code; foundational for the upcoming Conditions (if/else) chapters. [S1]

📖 세부 내용 (Details)

• Direct example: int x = 5; int y = 3; Console.WriteLine(x > y); // returns True because 5 is greater than 3. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

• 비교 결과가 진짜 bool 값으로 출력됨: C의 비교식은 사실 int(1 또는 0)를 반환하므로 printf로 직접 출력하면 1/0이 찍히지만, C#은 bool이 실질적인 타입이라 Console.WriteLine(x > y);가 "True"라는 단어 자체를 출력한다는 점이 확인됨 — Data Types 챕터에서 확인된 bool의 1급 타입 지위가 여기서 실제로 드러남. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — x > y 비교 결과를 직접 출력하는 예제가 원문에서 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Comparison operators return real bool values, printed as "True"/"False" (C#):

int x = 5;
int y = 3;
Console.WriteLine(x > y);  // "True"
