STL-pair-like triplet class - do I roll my own?

Question

I want to use a triplet class, as similar as possible to std::pair. STL doesn\'t seem to have one. I don\'t want to use something too heavy, like Boost. Is there some useful

Answer 1

To add the aspect of similarity to std::pair, you could define a class that has first, second and third. My guess is that in In that case you cannot avoid making a subclass of std::pair and add a 'third' member. It's a few lines of code.

Furthermore, if you often use these things with the same type, you could make twins and triplet classes as well. Easily made with C++-11's 'using', like:

template  using twins = std::pair;
