#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"
