    Myhash_map c1; 
    c1.insert(Myhash_map::make_value(L'a', 1)); 
    c1.insert(Myhash_map::make_value(L'b', 2)); 
    c1.insert(Myhash_map::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" using key_type 
    for (Myhash_map::iterator it = c1.begin(); it != c1.end(); ++it) 
        {   // store element in key_type object 
        Myhash_map::key_type val = it->first; 
 
        System::Console::Write(" {0}", val); 
        }
