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

Did *you* test it? How?

  #include <list>
  #include <iostream>
  int main()
  {
      std::list<int> foo;
      foo.push_back(1);
      foo.push_back(2);
      foo.push_back(3);
      foo.insert(foo.end(), foo.begin(), foo.end());
      for(std::list<int>::const_iterator i = foo.begin();
      i!=foo.end(); ++i) {
          std::cout << *i << '\n';
      }
      return 0;
  }
               
In what way am I wrong? I see no infinite loop. On my system this
prints 1 2 3 1 2 3 and that's also what I'd expect.
