hi, everyone. I am fresh at cgal. how can I print the coordinate of a point?

here is the test programe:

 

#include <CGAL/Exact_spherical_kernel_3.h>

 

typedef CGAL::Exact_spherical_kernel_3         Spherical_k;

 

typedef CGAL::Point_3<Spherical_k>             Point_3;
typedef CGAL::Sphere_3<Spherical_k>            Sphere_3;

 

int main() {

 

 Sphere_3 s1 = Sphere_3(Point_3(1.0,0.0,0.0), r);
 Sphere_3 s2 = Sphere_3(Point_3(-1.0,0.0,0.0), r);
 Sphere_3 s3 = Sphere_3(Point_3(0.0,0.0,1.0), r);

 

 std::vector< CGAL::Object > intersecs;
 CGAL::intersection(s1, s2, s3, std::back_inserter(intersecs));
 std::cout<<intersecs.size()<<std::endl;
 
 Point_3 pt3;
 assign(pt3, intersecs[0]); 

//how can I output the coordinate of point pt3?

 

 return 0;
}
