well an outputstream has the  << operator overloaded an inputstream has the >> operator overloaded.

with file streams you are reading and writing to/from a file. but with string streams you are reading or writing strings


-------------------------
ostringstream oss();

oss << "hello";
oss << " ";
oss << "world";

string s = oss.str();

assert(s == "hello world");

--------------------------

string s;
ostringstream oss(s);

oss << "hello";
oss << " ";
oss << "world";

assert(s == "hello world");

the first example shows you how to get the stored string, the second shows you how to associate the stream with a string.
