I think the promblem is in i-=2; This is to reduce i for ^Z symbol; idk how to fix this.



#include <iostream>
#include <algorithm>
#include <iomanip>
#include <math.h>
using namespace std;

int main()
{
    double num[1000];
    int i = 0;
    for (i; cin; i++)
    {
        cin >> num[i];

    }
    for (i-=2; i >= 0; i--)
    {

        cout << fixed << setprecision(4) << sqrt(num[i]) << endl;
    }
}
