How can I obtain the cube root in C++?

Question

I know how to obtain the square root of a number using the sqrt function.

How can I obtain the cube root of a number?

Answer 1

I would discourage any of the above methods as they didn't work for me. I did pow(64, 1/3.) along with pow(64, 1./3.) but the answer I got was 3
Here's my logic.

ans = pow(n, 1/3.);
if (pow(ans, 3) != n){
   ans++;
}
