operator== (hash_multiset) 

Tests if the hash_multiset object on the left side of the operator is equal to the hash_multiset object on the right side.


bool operator!==(
   const hash_multiset <Key, Traits, Allocator>& _Left,
   const hash_multiset <Key, Traits, Allocator>& _Right
);

Parameters

_Left

An object of type hash_multiset.

_Right

An object of type hash_multiset.

true if the hash_multiset on the left side of the operator is equal to the hash_multiset on the right side of the operator; otherwise false.

The comparison between hash_multiset objects is based on a pairwise comparison of their elements. Two hash_multisets are equal if they have the same number of elements and their respective elements have the same values. Otherwise, they are unequal.

In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information.

int main( )

   for ( i = 0 ; i < 3 ; i++ )

      s1.insert ( i );
      s2.insert ( i * i );
      s3.insert ( i );
   }

   if ( s1 == s2 )
      cout << "The hash_multisets s1 and s2 are equal." << endl;
   else
      cout << "The hash_multisets s1 and s2 are not equal." << endl;

   if ( s1 == s3 )
      cout << "The hash_multisets s1 and s2 are equal." << endl;
   else
      cout << "The hash_multisets s1 and s2 are not equal." << endl;
}

Output

The hash_multisets s1 and s2 are not equal.
The hash_multisets s1 and s2 are equal.
