set_intersection

[Giulio Veronesi]

Hi,

set<int> s1, s2, s3;
....
set_intersection(s1.begin(), s1.end(), s2.begin(), s2.end(), ???);

What do I put at place of ??? to get in s3 the intersection between s1
and s2?

Thanks in advance,
Giulio

Thanks in advance,

For instance: std::inserter( s3, s3.begin() )

You are very smart... but that page does not answer to my question.
Anyway, somebody else gave me the solution yet.

Thanks

The point is:
You have the worlds knowledge at your fingertips in the form of Web-sites.
There is even a search engine that can provide you with possible answers to your
questions and is very good in doing so. Especially if it comes to code examples
on how to use some features in C++. You just need to use it. Try it, it works
faster then typing a question in your newsreader and sending it to a group.
