What's the different between std::multimap<key, value> and

[fish]

I found that they have one key and multiple values which is unique.
Anyone supplement？

Well, aside from the different layout, std::set<value> enforces the
uniqueness of the value type, while the multimap may have multiple instances
of value. So, multiple instances of a value would have to be stored in
different multimap entries.

A more closer analogue to std::multimap<key, value> would be a std::map<key,
std::multiset<value> >.
