#include<iostream>
using namespace std;
int main()
{
    int n;
    cin>>n;
    float a[10000],s;
    for(int i=1;i<=n;i++)
    {
        cin>>a[i];
        s=s+a[i];
    }
    s=s/n;
    printf("%0.2f",s);
    return 0;

float 开成 double

s没有初始值

@叶洛洛 float开成int，然后s开成double并赋初值为0

想问一下为什么不能用float？

by 神啊波吃的 @ 2022-05-01 11:30:42

@Streetlights float的精度太小，double才是小数类型

精度问题

double是双精度

by FengYuXinMing @ 2022-09-15 19:38:57

float只支持9位小数（可能说错）
