Wanna talk about... std::set?

Question

Recently I find lack of lessons about STL in the c++.
Container std::set is an associative container and header that need to be include for it is,
#include <set>;
std::set is an associative container that contains a sorted set of unique objects of type Key.
Basic example:

As for me most relevante reference is:
http://www.cplusplus.com/reference/set/set/set/
