for( Surface::Facet_iterator fb = surface.facets_begin()
                  , fe = surface.facets_end()
                  ; fb != fe
                  ; ++ fb
                  ){         
         if( fb->is_triangle())
              std::cout << cont << " -TRIANGULAR ->" << order << "\n";
         else{
              std::cout << cont << " -NÃO TRIANGULAR ->" << order << "\n";
              break;
         }
 
         cont++;
}

fb is of type Surface::Facet_iterator. An iterator behaves approximately like 
pointers. The value type of that iterator type is facet. It means that you 
can 
do:
  Facet f = (*fe); // you need to _dereference_ "fe" with, "*"
or directly call Facet methods using:
  fb->method(...)
