2.26.4.Use polar to create complex number

#include <complex>

#include <iostream>



using namespace std;



int main( )  {

  double rho = 3.0; // magnitude

  double theta = 3.141592 / 2; // angle

  complex<double> coord = polar(rho, theta);

  cout << "rho = " << abs(coord) << ", theta = " << arg(coord) << endl;

  coord += polar(4.0, 0.0);

  cout << "rho = " << abs(coord) << ", theta = " << arg(coord) << endl;

}

rho = 3, theta = 1.5708
rho = 5, theta = 0.643501
