12.14.2.Create istream_iterator for reading int values from cin

#include <iostream>

using std::cout;

using std::cin;

using std::endl;



#include <iterator>



int main()

{

   cout << "Enter two integers: ";



   std::istream_iterator< int > inputInt( cin );



   int number1 = *inputInt; 

   ++inputInt;              

   int number2 = *inputInt; 



   std::ostream_iterator< int > outputInt( cout );



   cout << "The sum is: ";

   *outputInt = number1 + number2;

   cout << endl;

   return 0;

}

Enter two integers: 1 2
The sum is: 3

12.14.istream_iterator
	12.14.1.	Use istream_iterator
	12.14.2.	Create istream_iterator for reading int values from cin
	12.14.3.	Use istream_iterator and ostream_iterator to read from cin and write to cout.
	12.14.4.	Use istreambuf_iterator, ostreambuf_iterator, and replace_copy() to filter a file.
