map container question
Thank you. Zhuge. I will try the ">" overload.
But my question is the syntax. I would word the question differently.
By default, map container has the elements sorted in ascending order.
std::map<int, std::string, std::greater<int> > will sort the element in
descending order. But If I use class type as the key, what would be the syntax be? Some thing like
std::map<int, std::string, greater<key_class> > ?

You should look up operator overloading and overload the > operator for your key_c class.
Yes. it works after ">" overload. Also the syntax is
std::map<int, std::string, std::greater<key_class> >
Many thanks for the help.
