怎么会runtime error??????????#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int n,i,l[100];
int t=1,s=0,c=0,f;
double a;
cin>>n;
while(n--)
{
int m;
cin>>m;
f=m;
while(m--)
{
cin>>l[t++];
s+=l[t-1];
}
a=(double)s/f;
for(i=1;i<=f;i++)
{
if (l[i]>a) c++;
}
a=(double)c*100/f;
cout<<fixed<<setprecision(3)<<a<<"%"<<endl;
}
return 0;
}
到底哪个语句耗时间啊???
