+# [[C For Loop]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+The source frames the `for` vs `while` choice as a matter of KNOWING the iteration count in advance — "when you know exactly how many times you want to loop... use the for loop instead of a while loop" — meaning `for` isn't a functionally different tool from `while` (a `for` loop can always be rewritten as a `while`), it's a structural convention that bundles initialization, condition, and increment into one line specifically for the fixed-count use case. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`for (expr1; expr2; expr3) { ... }`** — expr1 runs once before the loop starts; expr2 is the continuation condition checked each iteration; expr3 runs after each iteration's body. [S1]
+- **Fixed-count use case** — the recommended tool when the number of iterations is known ahead of time, unlike `while`'s open-ended condition-driven repetition. [S1]
+- **Flexible step expressions** — expr3 isn't limited to `++`; any increment/decrement/step size works (`i = i + 2`, `i--`, etc.). [S1]
+
+## 📖 세부 내용 (Details)
+- Basic counting: `int i; for (i = 0; i < 5; i++) { printf("%d\n", i); }` — prints 0 to 4. [S1]
+- Custom step size for evens: `int i; for (i = 0; i <= 10; i = i + 2) { printf("%d\n", i); }`. [S1]
+- Accumulating a sum across iterations: `int sum = 0; int i; for (i = 1; i <= 5; i++) { sum = sum + i; } printf("Sum is %d", sum);`. [S1]
+- Countdown via decrement: `int i; for (i = 5; i > 0; i--) { printf("%d\n", i); }`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+1부터 5까지의 합을 for 루프로 누적 계산하는 예제(sum = sum + i)가 원문에서 직접 실전 활용 사례로 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Accumulating a running total across for-loop iterations (C):
+```c
+int sum = 0;
+int i;
+for (i = 1; i <= 5; i++) {
+  sum = sum + i;
+}
+printf("Sum is %d", sum);
+```
