[saiavinashiitr]

what does setw() function do??can u give an example...
when are <iomanip> and <sstream> header used???

setw is a manipulator. I can't answer this question unless you know about a) references, b) operator overloading, c) the std::basic_ostr eam class.

The sstream header is used with string streams. A string stream is an object that behaves like a stream.
