Please, I need to calculate the square root of integers. Do someone know how to do this?

I need to calculate the square root of integers...


//
// test_sqrt.cpp
//
#include "../code/nr3.h"

int main()
{
int i;
char c;
cout << "Enter an integer: ";
while (cin >> i) {
cout << "The square root of "
<< i << " is equal to "
<< sqrt(Doub(i)) << endl;

cout << endl << "Enter an integer: ";
}
cout << endl;
return 0;
}


Output:

$ g++ -Wall -W test_sqrt.cpp -o test_sqrt
$ ./test_sqrt
Enter an integer: 1
The square root of 1 is equal to 1

Enter an integer: 2
The square root of 2 is equal to 1.41421

Enter an integer: 3
The square root of 3 is equal to 1.73205

Enter an integer: 10
The square root of 10 is equal to 3.16228

Enter an integer: 100
The square root of 100 is equal to 10

Enter an integer: 1000
The square root of 1000 is equal to 31.6228

Enter an integer: 10000
The square root of 10000 is equal to 100

Enter an integer: 100000
The square root of 100000 is equal to 316.228

Enter an integer: 99
The square root of 99 is equal to 9.94987

Enter an integer: quit
