12.17.1.Attempt to read from empty stream

#include <iostream>

using std::cout;

using std::endl;



#include <string>

using std::string;



#include <sstream>

using std::istringstream;



int main()

{

   string input( "" );

   istringstream inputString( input );



   // attempt to read from empty stream

   long value;

   inputString >> value;



   if ( inputString.good() )

      cout << "\n\nlong value is: " << value << endl;

   else

      cout << "\n\ninputString is empty" << endl;





   return 0;

}

inputString is empty
