Why is here the runtime error on the 6 test?
What test is 6?

#include <iostream>
#include <cmath>
using namespace std;

void ghjkl(long double p)
{cout << fixed;
cout.precision(4);
cout << p << endl;}

int main() {
long double a[1000]={-1.0};
long long i=0;
while(cin)
{cin >> a[i];
i++;}
i=i-2;
long double b[1000];
for(int k=0; k<1000; k++)
{b[k]=sqrt(a[k]);}
for(int m=i; m>=0; m--)
{ghjkl(b[m]);}
return 0;
}
