Outcomes

• create and process a random-access, binary file
• use structs

Before Starting

The Assignment

Assumptions and restrictions

• The file you create that contains the hardware store database should be a binary, random-access file.
• Each of the operations on the database (inserting an item, listing all items, deleting an item, and updating the quantity of an item) should be implemented as separate functions.
• When updating an item in the database, you may assume that only the quantity of an item may be changed (you don't have to worry about updating any of the other information associated with an item).
• Your program does not have to initialize the database with the items listed on page 474; rather, the database file should be empty to begin with.
• You may assume that the user enters data from the keyboard correctly (your program does not have to check for incorrect input).

Include files

• stdio.h
• string.h if you use any of the string handling functions
