@chenruiming 代码呢

@chenruiming 这题直接相加然后除以人数就行，要用浮点型```

#include<iostream>
using namespace std;
int main()
{
    int n,i,l;
    double s=0;
    cin>>n;
    for(i=1;i<=n;i++){
    cin>>l;
    s=s+l;
    }
    printf("%0.2f",s/n);
}

@chenruiming 你源码中的h要用double或float 求关谢谢

@chenruiming ac code:

#include <cstdio>
using namespace std;

int main()
{
    int n;
    double s = 0.0;
    scanf("%d", &n);
    for (int i = 1; i <= n; i++)
    {
        int a;
        scanf("%d", &a);
        s += a;
    }

    printf("%.2lf\n", s / n);

    return 0;
}

求关注，qwq

小学知识，总数/人数=平均值

#include <bits/stdc++.h>
using namespace std;

int main() {
    double n, k, b = 0;
    cin >> n;
    for (int i = 0; i < n; i++) {
        cin >> k;
        b += k;
    }
    printf("%.2lf", b / n) ;
    return 0;
}
