Display vector in reverse order using reverse_iterator

 
 

#include <iostream>
using std::cout;
using std::endl;

#include <vector>
using std::vector;

int main()
{
   int array[ 6 ] = { 1, 2, 3, 4, 5, 6 }; // initialize array
   vector< int > integers; // create vector of ints

   integers.push_back( 2 );
   integers.push_back( 3 );
   integers.push_back( 4 );

   // two const reverse iterators
   vector< int >::const_reverse_iterator reverseIterator;
   vector< int >::const_reverse_iterator tempIterator = integers.rend();

   // Display vector in reverse order using reverse_iterator
   for ( reverseIterator = integers.rbegin();
      reverseIterator!= tempIterator; ++reverseIterator )
      cout << *reverseIterator << ' ';


   cout << endl;
   return 0;
}

/*
