comparison operators

function

template <class Key, class Compare, class Allocator>
  bool operator== ( const set<Key,Compare,Allocator>& x,
                    const set<Key,Compare,Allocator>& y );
template <class Key, class Compare, class Allocator>
  bool operator<  ( const set<Key,Compare,Allocator>& x,
                    const set<Key,Compare,Allocator>& y );

                    const set<Key,Compare,Allocator>& y );

  bool operator> ( const set<Key,Compare,Allocator>& x,
                    const set<Key,Compare,Allocator>& y );
template <class Key, class Compare, class Allocator>
  bool operator>= ( const set<Key,Compare,Allocator>& x,
                    const set<Key,Compare,Allocator>& y );
template <class Key, class Compare, class Allocator>
  bool operator<= ( const set<Key,Compare,Allocator>& x,
                    const set<Key,Compare,Allocator>& y );

Global comparison operator functions

These overloaded global operator functions perform the appropriate comparison operation between set containers x and y.

Operations == and != are performed by comparing the elements using algorithm equal.

Operations <, >, <= and >= are performed by using algorithm lexicographical_compare, which requires that the type of the elements (template parameter Key) has the < operation (less-than) defined between two objects of that type.

These operators are overloaded in header <set>.

Parameters

x, y: set containers, having both the same template parameters (Key, Compare and Allocator).

Return Value

true if the condition holds, and false otherwise.
