// Fig. 23.5: Fig23_05.cpp
// Demonstrating input and output with iterators.
#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <iterator> // ostream_iterator and istream_iterator

int main()
{
   cout << "Enter two integers: ";

   // create istream_iterator for reading int values from cin
   std::istream_iterator< int > inputInt( cin );

   int number1 = *inputInt; // read int from standard input
   ++inputInt; // move iterator to next input value
   int number2 = *inputInt; // read int from standard input

   // create ostream_iterator for writing int values to cout
   std::ostream_iterator< int > outputInt( cout );

   cout << "The sum is: ";
   *outputInt = number1 + number2; // output result to cout
   cout << endl;
