Description
includes() checks whether every member of a sorted sequence is a member of another sorted sequence. It implements the common set operation of checking whether a set is contained within another set.
Declaration
template <class In, class In2> bool includes(In, In, In2, In2); template <class In, class In2, class Cmp> bool includes(In, In, In2, In2, Cmp);
Concept
The sample checks whether vec2 is contained within vec1 (yes), and then whether vec1 is contained within vec2 (no).
