math operators

[DarkMoose]

Hihi. I'm in the middle of learning C++. Can any of you tell me how to get the square root of something? Like, in VB, you put Sqr(numberGoezHere). how do you do that in C++? and then, how do you raise something to a power?

The mathematical functions are in math.h, but if you're using the Standard Library (like most of us ), they're then in cmath:

#include <iostream>
#include <cmath>

using namespace std;

void main() {
    double x = 5;

    cout << sqrt(x) << endl;
}

To raise to a power, use pow.
