int main()   
    {   
    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]"   
    Myhash_map::const_iterator cit = c1.begin();   
    for (; cit != c1.end(); ++cit)   
        {   // get a const reference to an element   
        Myhash_map::const_reference cref = *cit;   
        System::Console::Write(" [{0} {1}]", cref->first, cref->second);
