checked_array_iterator::operator--

checked_array_iterator::operator--

 

Decrements the checked_array_iterator to the previous element.

checked_array_iterator<_Iterator>& operator--( );
checked_array_iterator<_Iterator> operator--( int );

The first operator returns the predecremented checked_array_iterator and the second, the postdecrement operator, returns a copy of the decremented checked_array_iterator.

For more information, see Checked Iterators.

Example

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

int main() {
   using namespace stdext;
   using namespace std;
   int a[] = {6, 3, 77, 199, 222};
   int b[5];
   copy(a, a + 5, checked_array_iterator<int*>(b,5));

   checked_array_iterator<int*> checked_output_iterator(b,5);

   cout << *checked_output_iterator << endl;
   checked_output_iterator++;
   cout << *checked_output_iterator << endl;
   checked_output_iterator--;
   cout << *checked_output_iterator << endl;
