+# [[CPP Assignment Operators]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+This chapter explicitly explains WHY these operators are called "compound" — they combine a regular operator (`+`, `-`, `*`, etc.) with the assignment operator (`=`) into ONE single operator (`+=` = `+` combined with `=`) — a naming rationale C's equivalent chapter never spelled out, even though the underlying expansion rule (`x OP= y` ≡ `x = x OP y`) is identical between the two languages. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`=`** — basic assignment. [S1]
+- **Compound assignment operators** — `+=`, `-=`, `*=`, `/=`, `%=`, `&=`, `|=`, `^=`, `>>=`, `<<=`, each expanding to `x = x <op> value`. [S1]
+- **"Compound" naming rationale** — explicitly explained as combining a regular operator with `=` into one operator symbol. [S1]
+- **Purpose** — pure shorthand for readability/brevity, especially when updating the same variable repeatedly. [S1]
+
+## 📖 세부 내용 (Details)
+- Basic compound usage: `int x = 10; x += 5; // same as x = x + 5 cout << x; // 15 x *= 2; // same as x = x * 2 cout << x; // 30`. [S1]
+- Real-life savings tracker: `int savings = 100; savings += 50; cout << "Total savings: " << savings;`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources). C 챕터와 동일한 확장 규칙이 확인되었으나, "compound"라는 명칭의 유래(연산자+대입 결합)를 이 챕터가 더 명시적으로 설명함.
+
+## 🛠️ 적용 사례 (Applied in summary)
+저축액에 50을 더하는 savings += 50 예제가 원문에서 직접 실전 활용 사례로 제시됨(계좌 잔액 누적 갱신). [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Tracking a running total using the compound addition-assignment operator (C++):
+```cpp
+int savings = 100;
+savings += 50; // add 50 to savings
+cout << "Total savings: " << savings;
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.84
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[C++ Tutorial]]
+- **관련 개념:** [[CPP Operators Arithmetic]], [[CPP Operators Comparison]], [[C Operators Assignment]]
+- **참조 맥락:** 대입 연산자 — 비교 연산자(Operators Comparison) 챕터로 이어짐.
