请把以下代码改写为c++语言：#includeiostreamusing namespace std;#includealgorithm#includecstdiobool cmpint a int b return a b;int main int n; cin n; int a35; for int i = 0; i n; i++ cin ai; int m; cin m;

#include #include #include

using namespace std;

bool cmp(int a, int b) { return a > b; }

int main() { int n; cin >> n; int a[35]; for (int i = 0; i < n; i++) { cin >> a[i]; } int m; cin >> m; sort(a, a + n, cmp); int sum = 0; for (int i = 0; i < m; i++) { sum += a[i]; } printf("%.2f\n", 1.0 * sum / m); return 0; }
