Example

// checked_iterators_op_diff.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>

int main() {
   using namespace std;   
   vector<int> V1;

   for (int i = 0; i < 10 ; i++)
      V1.push_back(i);

   // Declare a difference type for a parameter
   stdext::checked_iterator<vector<int> >::difference_type diff = 2;

   stdext::checked_iterator< vector<int> > VChkIter(V1, V1.begin());

   stdext::checked_iterator<vector<int> >::reference refrpos = VChkIter [diff];

   cout << refrpos + 1 << endl;
