Re: [Boost-users] Searching through a vector of tuples...

What would be a good method, using an stl algorithm, to search through the vector above to match only the int portion of the tuple (ignoring the double)?

Use std::find with a boost::transform_iterator over a function returning the first member of the tuple, then extract the resulting iterator's base() iterator. HTH, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
