Re: Best way to append std::list to itself

Hi,

what is the best way to insert the contents of std::list to the end of
the
same list? I haven't used C++ much recently (actually, in quite some
time)
and I can't tell if there's a much simpler way to achieve the
following
(the appending functionality - this is just an example) - assuming
it's
correct and portable and not just happening to work on my system.

#include<list>

struct A {
   std::list<type> list;

   void append(const std::list<type>& other)
   {
     if (&list !=&other) {
       list.insert(list.end(), other.begin(), other.end());
     } else if (!list.empty()) {
       std::list<type>::iterator end = list.end();
       --end;
       list.insert(list.end(), list.begin(), end);
       list.push_back(*end);
     }
   }
};
