operator>= (set)

Article

Tests if the set object on the left side of the operator is greater than or equal to the set object on the right side.

Syntax

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

Parameters

_Left
An object of type set.
_Right
An object of type set.

Return Value

true if the set on the left side of the operator is greater than or equal to the set on the right side of the list; otherwise false.

Remarks

The comparison between 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.

Example

// set_op_ge.cpp
// compile with: /EHsc
#include <set>
#include <iostream>

int main( )
{
   using namespace std;
   set <int> s1, s2, s3, s4;
   int i;

   for ( i = 0 ; i < 3 ; i++ )
   {
      s1.insert ( i );
      s2.insert ( i * i );
      s3.insert ( i - 1 );
      s4.insert ( i );
   }

   if ( s1 >= s2 )
      cout << "Set s1 is greater than or equal to set s2." << endl;
   else
      cout << "The set s1 is less than the set s2." << endl;

   if ( s1 >= s3 )
      cout << "Set s1 is greater than or equal to set s3." << endl;
   else
      cout << "The set s1 is less than the set s3." << endl;

   if ( s1 >= s4 )
      cout << "Set s1 is greater than or equal to set s4." << endl;
   else
      cout << "The set s1 is less than the set s4." << endl;
}

The set s1 is less than the set s2.
Set s1 is greater than or equal to set s3.
Set s1 is greater than or equal to set s4.
