+# [[C Multidimensional Arrays]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+A multidimensional array is defined as literally "an array of arrays," and this compounds directly into the looping requirement: an N-dimensional array needs exactly N nested loops to visit every element — a 2D array needs 2 nested loops (as shown), a 3D array would need 3 — meaning the loop-nesting depth isn't a stylistic choice but a direct structural consequence of how many dimensions the array has. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Multidimensional array** — "basically an array of arrays"; C supports any number of dimensions, with 2D being the most common. [S1]
+- **2D array (`type name[rows][cols]`)** — a matrix/table; first bracket = row count, second bracket = column count. [S1]
+- **Dual-index access** — `matrix[row][col]` addresses a specific cell; both indices are zero-based. [S1]
+- **One nested loop per dimension** — looping a 2D array fully requires 2 nested loops (outer for rows, inner for columns); a 3D array would require 3 nested loops. [S1]
+- **3D arrays (`type name[blocks][rows][cols]`)** — represent structures like multiple tables or game levels, each block itself being a 2D array. [S1]
+
+## 📖 세부 내용 (Details)
+- Creating and accessing a 2D array: `int matrix[2][3] = { {1, 4, 2}, {3, 6, 8} }; printf("%d", matrix[0][2]); // Outputs 2`. [S1]
+- Modifying a specific cell: `matrix[0][0] = 9; // Now outputs 9 instead of 1`. [S1]
+- Fully looping a 2D array with nested loops: `for (i = 0; i < 2; i++) { for (j = 0; j < 3; j++) { printf("%d\n", matrix[i][j]); } }`. [S1]
+- Declaring a 3D array (2 blocks × 4 rows × 3 columns): `int example[2][4][3];`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **차원 수와 중첩 루프 개수의 직접 대응**: 2차원 배열은 중첩 루프 2개, 3차원 배열은 중첩 루프 3개가 필요하다는 구조적 대응 관계가 명시적으로 확인됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+2D 배열은 점수표, 게임판, 스프레드시트에, 3D 배열은 여러 테이블의 집합이나 게임의 여러 레벨 같은 복잡한 구조 표현에 적합하다고 원문에서 직접 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Fully iterating a 2D array requires one nested loop per dimension (C):
+```c
+int matrix[2][3] = { {1, 4, 2}, {3, 6, 8} };
+int i, j;
+for (i = 0; i < 2; i++) {
+  for (j = 0; j < 3; j++) {
+    printf("%d\n", matrix[i][j]);
+  }
+}
+```
