Re: [Boost-users] Copy elements from one STL container to another STL container

In Stroustrup's book "The C++ Programming Language -- 3rd edition",  
18.6 is "Modifying Sequence Algorithms".  18.6.1 is "Copy".  He talks  
about what is in the standard and then gives an example almost what  
you are asking for.

You could also use the standard Copy (described in 25.2.1 of the  
standard) and compute the "InputInterator last" using your criterial  
before doing the copy.  Yes, that does make two passes but any test  
inside the copy loop will cost almost the same.
