operator> (<iterator>)
Tests if the iterator object on the left side of the operator is greater than the iterator object on the right side.
template<class RandomIterator>
bool operator>(
const reverse_iterator<RandomIterator>& _Left,
const reverse_iterator<RandomIterator>& _Right
);
Parameters
_Left
An object of type iterator._Right
An object of type iterator.
Return Value
true if the iterator on the left side of the expression is greater than the iterator on the right side of the expression; false if it is less than or equal to the iterator on the right.
Remarks
One iterator object is greater than another if it addresses an element that occurs later in the container than the element addressed by the other iterator object. One iterator object is not greater than another if it addresses either the same element as the other iterator object or an element that occurs earlier in the container than the element addressed by the other iterator object.
Example
// iterator_op_gt.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
int i;
vector<int> vec;
for (i = 0 ; i < 6 ; ++i ) {
vec.push_back ( 2 * i );
}
vector <int>::iterator vIter;
cout << "The initial vector vec is: ( ";
for ( vIter = vec.begin( ) ; vIter != vec.end( ); vIter++)
cout << *vIter << " ";
cout << ")." << endl;
vector <int>::reverse_iterator rVPOS1 = vec.rbegin ( ),
rVPOS2 = vec.rbegin ( );
cout << "The iterators rVPOS1 & rVPOS2 initially point to "
<< "the first element\n in the reversed sequence: "
<< *rVPOS1 << "." << endl;
if ( rVPOS1 > rVPOS2 )
cout << "The iterator rVPOS1 is greater than "
<< "the iterator rVPOS2." << endl;
else
cout << "The iterator rVPOS1 is less than or "
<< "equal to the iterator rVPOS2." << endl;
rVPOS1++;
cout << "The iterator rVPOS1 now points to the second "
<< "element\n in the reversed sequence: "
<< *rVPOS1 << "." << endl;
if ( rVPOS1 > rVPOS2 )
cout << "The iterator rVPOS1 is greater than "
<< "the iterator rVPOS2." << endl;
else
cout << "The iterator rVPOS1 is less than or "
<< "equal to the iterator rVPOS2." << endl;
}
The initial vector vec is: ( 0 2 4 6 8 10 ). The iterators rVPOS1 & rVPOS2 initially point to the first element in the reversed sequence: 10. The iterator rVPOS1 is less than or equal to the iterator rVPOS2. The iterator rVPOS1 now points to the second element in the reversed sequence: 8. The iterator rVPOS1 is greater than the iterator rVPOS2.
