Simple Stringstream

[Zincott]

Quick question:

// example about structures
#include <iostream>
#include <string>
#include <sstream>
using namespace std;

struct movies_t {
  string title;
  int year;
} mine, yours;

void printmovie (movies_t movie);

int main ()
{
  string mystr;

  mine.title = "2001 A Space Odyssey";
  mine.year = 1968;

  cout << "Enter title: ";
  cin >> yours.title;
  cout << "Enter year: ";
  cin >> mystr;
  stringstream(mystr) >> yours.year;

  cout << "My favorite movie is:\n ";
  printmovie (mine);
  cout << "And yours is:\n ";
  printmovie (yours);
  return 0;
}

void printmovie (movies_t movie)
{
  cout << movie.title;
  cout << " (" << movie.year << ")\n";
}

This is another example from the tutorial on this website (very slightly manipulated). Basically, I want to know if IN GENERAL (not just in this situation), "stringstream" -- on line 25 (the bold/underlined line) -- is used to change strings to data structures.

***(YES/NO), if no then what else***

Stringstream converts string into stream.Then it can be used like we use cin, cout or file objects.

Its generally used to extract other type(int generall) from string.stringstream(mystr) >> yours.year; gets years of int type from myster.

IN GENERAL (not just in this situation), "stringstream" -- on line 25 (the bold/underlined line) -- is used to change strings to data structures.

Certainly not. It is slow and supports only limited format options.

Okay got it. Thanks.
