1- A stringstream associates a string object with a stream allowing 
2you to read from the string as if it were a stream (like cin).
3- Method:
4 clear() — to clear the stream
5 str() — to get and set string object whose content is present in stream.
6 operator << — add a string to the stringstream object.
7 operator >> — read something from the stringstream object,

1// EXAMPLE
2ostringstream ssTextAsStream("This is part of the stream."); // declare ostringstream
3string sTextAsString = ssTextAsStream.str(); // converted to string
4cout << sTextAsString << "\n"; // printed out
