graph.h

Hi,
Im using Microsoft Visual C++ 2005 Express Edition to write my C applications (I hardly use C++).
Im trying to run the following code, but apprently not all the necessary headers are standard included with my version of Visual C++.
Can anyone please tell me how / where to get all necessary files to run this and similar codes and how to install them?
Thanks. <font color="#0000ff" size=2>
