asking about pipe line

hi, all
the information I get from the pipe line is the same to that I input
into the pipe
what is wrong with this piece of code?
how to change it?
thanks.

// tryPipe3.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "tryPipe3.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#endif
