题干有点问题 及格成绩：60 优秀成绩：85 ``` #include <cstdio> int main(){ int n, x, mi = 0, mx = 0; scanf("%d", &n); int total = n; while(n--){ scanf("%d", &x); if(x >= 60) mi++; if(x >= 85) mx++; } printf("%d%%\n", (int)(((float)mi / total) * 100 + 0.5)); printf("%d%%\n", (int)(((float)mx / total) * 100 + 0.5)); return 0; } ```

```cpp #include <bits/stdc++.h> using namespace std; #define int long long // #define LL long long #define endl '\n' void solve() { int n; cin >> n; double pass = 0, good = 0; for (int i = 1; i <= n; i++) { int score; cin >> score; if (score >= 85) { pass++; good++; } else if (score >= 60) pass++; } printf("%.lf%c\n%.lf%c", pass / n * 100, '%', good / n * 100, '%'); } signed main() { // ios::sync_with_stdio(0); // cin.tie(0), cout.tie(0); solve(); return 0; } ```
