hi 
I need visit face in Triangulation, I read manual cgal ,but output example
is ambiguous ,and I need for visit all face by iterator but error Occurs,
line error in program is:  std::cout << *vit1<std::endl;//error is 
#include "stdafx.h"
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Delaunay_triangulation_3.h>
#include <CGAL/Triangulation_vertex_base_with_info_3.h>
#include <CGAL/IO/Color.h>
#include <fstream>
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef CGAL::Triangulation_vertex_base_with_info_3<CGAL::Color, K> Vb;
typedef CGAL::Triangulation_data_structure_3<Vb> Tds;
typedef CGAL::Delaunay_triangulation_3<K, Tds> Delaunay;
typedef Delaunay::Point Point;
//typedef TriangulationDataStructure 3::Facet Facet;
int main()
{
Delaunay T;
char ch;
T.insert(Point(0,0,0));
T.insert(Point(1,0,0));
T.insert(Point(0,1,0));
T.insert(Point(0,0,1));
T.insert(Point(2,2,2));
T.insert(Point(-1,0,1));
// Set the color of finite vertices of degree 6 to red.
Delaunay::Finite_vertices_iterator vit;
 std::ofstream oFileT("output_tds.txt",std::ios::out);
 oFileT<<T;
std::ifstream oFileT1("output_tds.txt",std::ios::in);
oFileT1>>T;
std::cout<<T;
for (vit = T.finite_vertices_begin(); vit != T.finite_vertices_end(); ++vit)
{
if (T.degree(vit) == 6)
vit->info() = CGAL::RED;
std::cout << *vit<<std::endl;
}
Delaunay::Finite_facets_iterator vit1;
for (vit1= T.finite_facets_begin(); vit1 != T.finite_facets_end(); ++vit1)
std::cout << *vit1<std::endl;//error is 
std::cin>>ch;
return 0;
}
please help me in structure triangulation and output.thanks.
