12.18.4.Output of several data types to an ostringstream object: double, int and address of int

#include <iostream>

using std::cout;

using std::endl;



#include <string>

using std::string;



#include <sstream>

using std::ostringstream;



int main()

{

   ostringstream outputString;



   string string1( "string " );

   double double1 = 123.4567;

   int integer = 22;



   outputString << string1 << double1  << integer << &integer;



   // call str to obtain string contents of the ostringstream

   cout << "outputString contains:\n" << outputString.str();



   return 0;

}

outputString contains:
string 123.457220x22fe74"
