# [[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 `printf`로 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#):
```csharp
int x = 5;
int y = 3;
Console.WriteLine(x > y);  // "True"
```
