I gave up with developing my first big program, so i told myself to visit you hoping for some help.

The problem is A "Library Cataloging System", It consists of records and the user is allowed to add, remove and update an existing record, the file should be encrypted/ decrypted and it's shouldn't work only on one harddisk, by checking the Serial Number.

So Step one :
Variables :

Book_Id
Book_Name
Book_Author
Book_PublishingDate


Next come the Functions: How many and what tasks needs to be assigned a function???

PLease help, even with one word, because i'm really a bad programmer
