operator>= (hash_set)
Tests if the hash_set object on the left side of the operator is greater than or equal to the hash_set object on the right side.
bool operator!>=(
const hash_set <Key, Traits, Allocator>& _Left,
const hash_set <Key, Traits, Allocator>& _Right
);
Parameters
_Left
An object of type hash_set._Right
An object of type hash_set.
Return Value
true if the hash_set on the left side of the operator is greater than or equal to the hash_set on the right side of the list; otherwise false.
Remarks
The comparison between hash_set objects is based on a pairwise comparison of their elements. The greater than or equal to relationship between two objects is based on a comparison of the first pair of unequal elements.
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.
Example
// hash_set_op_ge.cpp
// compile with: /EHsc
#define _DEFINE_DEPRECATED_HASH_CLASSES 0
#include <hash_set>
#include <iostream>
int main( )
{
using namespace std;
using namespace stdext;
hash_set <int> hs1, hs2, hs3, hs4;
int i;
for ( i = 0 ; i < 3 ; i++ )
{
hs1.insert ( i );
hs2.insert ( i * i );
hs3.insert ( i - 1 );
hs4.insert ( i );
}
if ( hs1 >= hs2 )
cout << "hs1 greater than or equal to hs2" << endl;
else
cout << "hs1 less than hs2" << endl;
if ( hs1 >= hs3 )
cout << "hs1 greater than or equal to hs3" << endl;
else
cout << "hs1 less than hs3" << endl;
if ( hs1 >= hs4 )
cout << "hs1 greater than or equal to hs4" << endl;
else
cout << "hs1 less than hs4" << endl;
}
hs1 less than hs2
hs1 greater than or equal to hs3
hs1 greater than or equal to hs4
