int main() 
    { 
    Mymap c1; 
    c1.insert(Mymap::make_value(L'a', 1)); 
    c1.insert(Mymap::make_value(L'b', 2)); 
    c1.insert(Mymap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    Mymap::const_iterator cit = c1.begin(); 
    for (; cit != c1.end(); ++cit) 
        {   // get a const reference to an element 
        Mymap::const_reference cref = *cit; 
        System::Console::Write(" [{0} {1}]", cref->first, cref->second); 
        }
