Example of Stringstreams

Here is an example of stringstream that I picked up from here and modified it slightly.

//Program tested on Microsoft Visual Studio 2008 - Zahid Ghadialy
//Simple example of C++ stringstreams

#include<iostream>
#include<sstream>
#include<string>

using namespace std;

int main()
{
  string input;

  cout<< "Please enter some numbers speretaed by space and press enter once done: ";
  getline(cin, input);

  cout<< "input = " << input << endl;

  stringstream memString(input, ios_base::in); //stringstream( string s, openmode mode )

  cout<<"memString = " << memString << endl;
  cout<<"memString (contents) = " << memString.str() << endl;

  double summ = 0; 
  double temp;
  while (memString >> temp)
  { 
    summ+= temp;
  }

  cout<<"summ = " << summ << endl;

  return 0;
}

The output is as follows:
