Any STL data structure like pair that gives three items(types) instead of two?

Question

Question 1: I'm using C++ 11, and I'm learning. I realize I can do this with two pairs: ``` pair, <#class _T2#>>, <#class _T3#>> ``` Is that the best way? Question 2: If I don't need different types, so same type for two items, is it a waste to use pair, what should I use then? For three items? (again same type)

Accepted Answer

Use a `std::tuple`: ``` std::tuple<_T1, _T2, _T3> ``` Note that `std::tuple`s support an arbitrary amount of types stored in them. Also, to access the elements, you can't do the nice `pair.first`/`pair.second`, you have to use the syntax `std::get(tuple)`, where `n` is the element you want to retrieve.
