十几个评测点，一眼望去全部都是WA
求大佬帮忙看看代码错在哪里
代码如下：
# include<iostream>
# include<iomanip>
using namespace std;
int main(){
int num;cin>>num;
int a;
int sum=0;
for (int i=1;i<=num;i++){
cin>>a;
sum=sum+a;
}
cout<<fixed<<setprecision(2)<<sum/num<<endl;
}他给的是：too short on line one
求帮助！

样例过了吗

@sixer_120201
输出改成 out<<fixed<<setprecision(2)<<sum*1.0/num<<endl;
因为 sum 是整数类型的。
by xudongyi1 @ 2023-10-19 20:18:54
cout<<fixed<<setprecision(2)<<sum*1.0/num<<endl;
刚刚错了
