# [[C Tutorial]]

## 🎯 한 줄 통찰 (One-line insight)
Map of Content (MOC) for the W3Schools C Tutorial — the root that links every core C knowledge page in this topic folder. [S1]

## 🧠 핵심 개념 (Core concepts)
- This folder (`Topic_C`) wikifies the C programming language tutorial, one knowledge page per document, in P-Reinforce v3.1 format — same convention as `Topic_SQL` / `Topic_Python` / `Topic_Java` / `Topic_PHP` / `Topic_W3CSS` / `Topic_HTML` / `Topic_CSS` / `Topic_JavaScript`. [S1]
- **Scope**: tutorial + "Learning by examples" pages only. **Excluded**: `c_challenges_*` (18 code-challenge pages), `c_compiler`/`c_examples`/`c_exercises`/`c_practice`/`c_projects`/`c_quiz`/`c_exam`/`c_interview_questions`/`c_study_plan`/`c_syllabus`/`c_real_life_examples` (meta/index pages), `c_ref_*` (7 reference-dump pages: ctype, keywords, math, reference, stdio, stdlib, string, time). [S1]
- **97 of 97 planned docs complete — C category done.**
- Every page roots its Knowledge Graph back to this `[[C Tutorial]]` node.
