+# [[C Special Characters]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+A literal double-quote inside a double-quoted string is fundamentally AMBIGUOUS to the compiler — `"We are the so-called "Vikings" from the north."` looks like three separate adjacent strings, not one string containing quotes — so `\"` isn't just a stylistic escape, it's the only way to disambiguate where the enclosing string actually ends. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **The core problem** — double quotes delimit C strings, so a literal `"` inside one prematurely ends the string as far as the compiler is concerned. [S1]
+- **Core escape sequences** — `\'` (single quote), `\"` (double quote), `\\` (literal backslash). [S1]
+- **Other common escapes** — `\n` (newline), `\t` (tab), `\0` (null terminator). [S1]
+- **Backslash as the universal escape prefix** — turns the following character into a literal string character rather than a syntactic delimiter. [S1]
+
+## 📖 세부 내용 (Details)
+- Escaping double quotes inside a string: `char txt[] = "We are the so-called \"Vikings\" from the north.";`. [S1]
+- Escaping a single quote: `char txt[] = "It\'s alright.";`. [S1]
+- Escaping a literal backslash: `char txt[] = "The character \\ is called backslash.";`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 큰따옴표가 포함된 인용문(예: "Vikings")을 문자열에 그대로 담아야 할 때 \" 이스케이프가 실전에서 바로 쓰인다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Escaping a literal double quote so it doesn't prematurely end the string (C):
+```c
+char txt[] = "We are the so-called \"Vikings\" from the north.";
+```
