docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

+# [[CPP Structures (struct)]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Once a C++ struct is given a NAME (`struct car {...};`), that name alone becomes a usable data type — `car myCar1;` needs NO `struct` keyword before it — a direct contrast to C, where `struct car myCar1;` always requires the `struct` keyword UNLESS a separate `typedef` is used; meaning C++ eliminated an entire chapter's worth of C's typedef-with-struct workaround by making named structs behave as first-class types automatically. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Structure (`struct`)** — groups multiple MIXED-type variables ("members") into one unit; unlike C, members can include `string` directly. [S1]
+- **Anonymous struct + variable in one declaration** — `struct { int myNum; string myString; } myStructure;` declares the type AND the variable together, with no reusable name. [S1]
+- **Multiple variables of one anonymous struct** — `struct {...} myStruct1, myStruct2, myStruct3;` — comma-separated. [S1]
+- **Named structs behave as data types with NO `struct` prefix needed** — `struct car {...}; car myCar1;` — unlike C, which always requires writing `struct car myCar1;` unless `typedef` is used. [S1]
+- **Dot syntax (`.`)** — accesses/assigns individual members, same as C. [S1]
+
+## 📖 세부 내용 (Details)
+- Anonymous struct with a single variable: `struct { int myNum; string myString; } myStructure; myStructure.myNum = 1; myStructure.myString = "Hello World!";`. [S1]
+- Named struct usable as a type with no `struct` keyword at the use site: `struct car { string brand; string model; int year; }; car myCar1; myCar1.brand = "BMW";`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **이름 붙은 구조체는 struct 키워드 없이 타입처럼 사용 가능**: C에서는 typedef 없이는 항상 struct car myCar1;처럼 struct를 붙여야 했지만, C++에서는 struct car {...}; 선언 후 car myCar1;만으로 충분하다는 점이 명시적으로 확인됨 — C의 typedef-with-struct 챕터가 해결하던 문제를 C++는 언어 차원에서 이미 해결한 셈. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+Car 구조체 하나로 BMW와 Ford 두 대의 서로 다른 자동차 정보를 저장하는 예제가 원문에서 직접 실전 활용 사례로 제시됨(하나의 named struct, 여러 인스턴스). [S1]
+
+## 💻 코드 패턴 (Code patterns)
+A named struct used directly as a type, with no "struct" keyword needed at the declaration site (C++):
+```cpp
+struct car {
+  string brand;
+  string model;
+  int year;
+};
+int main() {
+  car myCar1;  // no "struct" prefix needed
+  myCar1.brand = "BMW";
+  myCar1.model = "X5";
+  myCar1.year = 1999;
+  return 0;
+}
+```
