boost tuple Vs stl pair

[Rui Maciel]

If you are faced with the need for a one-off, temporary tuple object to store a
pair of objects, between boost's tuple and stl's pair, what is the best library for
the job?


Thanks in advance,

It all depends if you want a boost dependency or not.  If you are already
using boost it makes no difference but even then I would still use the
std:air in preference to a tuple of two items.

Yeah, if you're trying to get 1st place during amateur hour.

In your opinion, what's the relation between std:air and a "1st place during amateur hour" ?

The added dependency is indeed a negative point. Nonetheless, other than that, is
there anything that makes one of those libraries better than the other?

IIRC, tuple is available in std::tr1 on some compilers.

Depends on the usage. The pairs first/second members may be easier to
comprehend, tuple's get<n> may be more amenable to template coding, and
of course is extensible beyond a pair.
