### 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
