c++ STL set difference

Question

Does the C++ STL set data structure have a set difference operator?

Answer 1

Not an "operator" in the language sense, but there is the set_difference algorithm in the standard library:

Of course, the other basic set operations are present too - (union etc), as suggested by the "See also" section at the end of the linked article.
