Pointers to elements of std::vector and std::list

Question

I\'m having a std::vector with elements of some class ClassA. Additionally I want to create an index using a std::map

Answer 1

1. for vectors no.

2. for lists yes. how? iterator works as a pointer to a particular node in the list. so you can assign values to any struct like:

   list mylist;

   pair< list::iterator ,int > temp;

   temp = make_pair( mylist.begin() , x );
