Family ) { cout << pair.first << represented by object at << (void*)pair.second << \n;

By using a for loop, you can iterate through a map in c++ and access the elements of the map one by one. Just like any other iterator type, the map iterator behaves like a pointer to a collection element, and for map, this is a std::pair, where first maps to the key and. Here is a simple way of doing it in c++11:
