1. Run Microsoft Visual C++ (typically 6.0)
2. Choose "File" from the main menu and then click "Open".
3. Navigate to the place (folder/directory) where you stored 
ider.cpp (the C++ source code file that you downloaded) and click "Open" button.
4. Choose "Build" from the main menu and then click "Build".
5. When you're prompted to create a default project workspace, click "Yes".
6. You will see the compiling results in the output window, 
typically you will see messages like the ones below:

Compiling...
ider.cpp
Linking...

ider.exe - 0 error(s), 0 warning(s)

7. Congratulation. You've finished the compiling.
8. Now in the same directory (folder) where you stored the ider.cpp,
you will find a new directory called "Debug". Open it and you will 
find an executable file called "ider.exe".
9. Copy the file to c:\ (your c drive).
10. Go to "Start" --> "Run" and type in "cmd", then press Enter. 
You will see a DOS window.
11. Type "cd c:\" and press Enter.
12. Type "ider xxxxxxxxx" (where you will put the 9 digits of your
Social Security Number instead of xxxxxxxxx) and press Enter. 
You will see the messages as the ones below:

    SSN_NUM: xxxxxxxxx
    Your unique class id is yyyyyyyy

13. The value of yyyyyyyy will represent your unique class id. 
Write it down and remeber it, since it will be used throughout the
quarter in your CS317 class. A file called "ID.txt" will be created
in the root directory (folder) "c:\", which contains the yyyyyyyy for 
your own backup.
14. Send your name and the id in an email to the instructor and the TAs.
