c++ sqrt

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

int main() {
    double x;
    cout << "Enter a number : ";
    cin >> x;

    double result = sqrt(x);
    cout << "sqrt(" << x << ") : " << result << endl;
}
	
	Enter a number : 5
sqrt(5) : 2.23607

Enter a number : 16
sqrt(16) : 4
