This tutorial shows you how to use set_intersection. set_intersection is defined in header algorithm. computes the intersection of two sets set_intersection can be used in the following way: Constructs a sorted range beginning in the location pointed by result with the set intersection of the two sorted ranges [first1,last1) and [first2,last2). The intersection of two sets is formed only by the elements that are present in both sets. The elements copied by the function come always from the first range, in the same order.
