docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영. - Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들 (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거. - Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/ Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/ Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이 존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존). - Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/ JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동. - 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리. - Topic_Programming 최종 문서 수: 2784 → 3985.

# [[CPP Data Structures]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
C has exactly ONE built-in data structure — the array — and everything else (linked lists, stacks, queues, hash-like maps) must be hand-built from structs and raw pointers; C++'s STL instead ships vector/list/stack/queue/deque/set/map as ready-made template classes, meaning the entire "how do I build a linked list" problem that consumed a whole chapter of Topic_C's Pointers section is simply gone from the C++ mental model — replaced by "which header do I include." [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **STL (Standard Template Library)** — a library of data structures + algorithms bundled with C++, used to store and manipulate data efficiently. [S1]
|
||||
- **Containers** — data structures that store data (vector, list, stack, queue, deque, set, map). [S1]
|
||||
- **Iterators** — objects used to access elements of a container without knowing its internal layout. [S1]
|
||||
- **Algorithms** — functions like `sort()` and `find()` that operate on containers through iterators. [S1]
|
||||
- **One header per container** — each container requires its own `#include` (`<vector>`, `<list>`, `<set>`, `<map>`, `<stack>`, `<queue>`), unlike arrays which need no header. [S1]
|
||||
- **Choosing a container is a design decision** — the right data structure + algorithm makes a program run faster, especially at scale; the table of 7 containers (Vector/List/Stack/Queue/Deque/Set/Map) each optimize a different access pattern. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
- Container comparison table: Vector (array-like, dynamic size, index access), List (sequential, add/remove both ends, no index access), Stack (LIFO, top only), Queue (FIFO, front/back only), Deque (double-ended, index access), Set (unique elements, no index), Map (key/value pairs, access by key). [S1]
|
||||
- Minimal vector usage: `vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"}; for (string car : cars) { cout << car << "\n"; }`. [S1]
|
||||
- Containers + iterators + algorithms form a triangle: a container without an algorithm to search/manipulate it is not very useful, and an algorithm needs a container to operate on. [S1]
|
||||
|
||||
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
||||
- **C에는 없는 개념 층위가 통째로 추가됨**: Topic_C에는 "자료구조 챕터"가 존재하지 않았고(배열이 유일한 내장 자료구조), 연결 리스트/스택/큐는 포인터+구조체로 직접 구현하는 예제들이 Pointers 섹션에 흩어져 있었다. C++는 이를 컨테이너+반복자+알고리즘이라는 3층 구조로 라이브러리화했다는 점이 이번 챕터에서 명확히 드러남. [S1]
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
현재 발견된 실제 적용 사례가 없습니다 — 문자열 vector를 만들고 for-each로 순회하는 패턴이 원문에서 STL 소개 예제로 제시됨. [S1]
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Required headers per container, and a first vector example (C++):
|
||||
```cpp
|
||||
#include <vector>
|
||||
#include <list>
|
||||
#include <set>
|
||||
#include <map>
|
||||
#include <stack>
|
||||
#include <queue>
|
||||
|
||||
vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"};
|
||||
for (string car : cars) {
|
||||
cout << car << "\n";
|
||||
}
|
||||
```
