用C++计算护盾防御力值低于平均值的护盾个数

```cpp #include <iostream> using namespace std; const int MAXN = 100; int a[MAXN][MAXN]; int main() { int n; cin >> n; int sum = 0; // 输入矩阵并计算元素总和 for (int i = 0; i < n; i++) { for (int j = 0; j < n; j++) { cin >> a[i][j]; sum += a[i][j]; } } double average = (double)sum / (n * n); int count = 0; // 统计防御力值小于平均值的元素个数 for (int i = 0; i < n; i++) { for (int j = 0; j < n; j++) { if (a[i][j] < average) { count++; } } } cout << count << endl; return 0; } ``` ######[AI问答 | 256点数解答 | 2026-03-28 20:16:19]
