Question

How to use cbrt() function to get the cubic root of N in C++

Answer 1

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
	double n = 27, rv;
	
	rv = cbrt(n);

	cout << "cbrt(" << n << ") = " << rv << endl;
	cout << "cbrt(-0.125) = " << cbrt(-0.125) << endl;
	cout << "cbrt(1000.0) = " << cbrt(1000.0) << endl;

	return 0;
}

// 3 * 3 * 3 = 27
// 10 * 10 * 10 = 1000

/*
run:

cbrt(27) = 3
cbrt(-0.125) = -0.5
cbrt(1000.0) = 10
