在讨论《第二个wa了请问为什么》回复：

@[WangJingze](/user/439743) 好的谢谢

```c #include int main() { int a, i = 1; scanf("%d", &a); do { a = a / 2; i++; } while (a > 1); printf("%d\n", i); return 0; } ```

```c #include int main() { int n, k, i, a[10000]; float sum1=0,sum2=0; scanf("%d %d", &n, &k); int p = 0; for (i = 0; i < n; i++) { a[i] = i + 1; if (a[i] % k =…
