Problems with compiling

[__gini2]

I downloaded a simple database management system from planet source code and tried compiling it but the error below pops up. This code is compiled using turboc3.0.How do i correct this error so that i can run this program effectively without bugs?

DATABASE.CPP
c:\unzipped\simple database management system\database\database.cpp(27) : fatal error C1083: Cannot open include file: 'c:\database\vdu.h': No such file or directory
Error executing cl.exe.

DATABASE.OBJ - 1 error(s), 0 warning(s)

I have the header file vdu.h(given by the writer of this source code), but i do not know how do i set the path for it so that there would not be any errors popping up.

According to the writer of this code, i should include the files data.dat and vdu.h in the correct path. But the file data.dat cannot be used because i do not have the appropriate program to open up this file. What do i have to do to be able to open and run this file(data.dat)?

There is another file, demo.cpp, which is also included together with this file, and is a demo of how the vdu.h file is used. This file also has compilation problems, and the error below pops up when i try to compile it.
