What will be the output of the following C++ code?

#include <iostream>
#include <complex>
using namespace std;
int main()
{
	complex <double> cn(3.0, 5.0);
	cout<<"Complex number with magnitude "<<abs(cn)<<" 
        and phase angle "<<arg(cn)<<" is: 
        "<<polar(abs(cn), arg(cn))<<endl;
	return 0;
}
