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

int main()
{
int num;
float root;
ifstream in_stream;
ofstream out_stream;
in_stream.open(\"Lab9B.in\");
if(in_stream.fail())
{
cout << \"ERROR: Unable to open file: Lab9B.in\" << endl;
exit(EXIT_FAILURE);
}
  
out_stream.open(\"Lab9B.out\");
if(out_stream.fail())
{
cout << \"ERROR: Unable to open file: Lab9B.out\" << endl;
exit(EXIT_FAILURE);
}
  
while(in_stream >> num)
{
root = sqrt(num);
  
out_stream << std::left;
out_stream << setprecision(5);
out_stream << setw(15);
out_stream << root << endl;
}
  
in_stream.close();
out_stream.close();
  
return 0;
