Writing square root in cplusplus

[kbz8]

Hi,
square root is in math.h (C include) or cmath (C++ version of math.h) and is a function named sqrt.

#include <cmath>
#include <iostream>

int main()
{
    int x = 25;
    std::cout << sqrt(x) << std::endl;
    return 0;
}

output : 5

Hello kbz8,

Now that you have changed your post to the code of someone else. Do you have a question?
