=====set_intersection===== Syntax: #include template< typename InIterA, typename InIterB, typename OutIter > OutIter set_intersection( InIterA start1, InIterA end1, InIterB start2, InIterB end2, OutIter result ); template< typename InIterA, typename InIterB, typename OutIter, typename StrictWeakOrdering > OutIter set_intersection( InIterA start1, InIterA end1, InIterB start2, InIterB end2, OutIter result, StrictWeakOrdering cmp ); The set_intersection() algorithm computes the intersection of the two sets defined by [start1,end1) and [start2,end2) and stores the intersection starting at result. Both of the sets, given as ranges, must be sorted in ascending order. The return value of set_intersection() is an iterator to the end of the intersection range. set_intersection() runs in [[/complexity|linear time]]. If the strict weak ordering comparison function object cmp is not specified, set_intersection() will use the < operator to compare elements.
