求大佬看看我哪里错了

#include <bits/stdc++.h>
using namespace std;
int main(){
    double a[1002], n, sum = 0;
    cin>>n;
    for (int i = 0; i < n; i++) cin>>a[i];
    sort(a, a + n);
    for (int i = 1; i < n - 1; i++) sum += a[i];
    printf("%.1lf", sum/n);
    return 0;
}

@chenqile 仔细读题，他让你保留两位小数。

    printf("%.2lf", sum/(n-2));
    return 0;

怎么还是ce

by 7The_shy @ 2023-12-22 19:28:56

1.n不能为double

2.输出的时候n应该减去两人

3.保留两位应该是“%.2lf”

@chenqile ？IDE 上没有 CE。

by xiaoshumiao @ 2023-12-22 19:30:23

@7The_shy 不过 n 硬要开 double 也没事。

by 7The_shy @ 2023-12-22 19:31:12

不过本地会报错
