    Hopefully the file already exists, but we're basically talking about a binary file where every record is exactly the same size. This way you can calculate an offset with the hash function.

    >Also, do I still need to use an array of any sort or not with hash files?
    You only need to work with a single record at a time, so no.

    My best code is written with the delete key.

    Of course. The only real difference between a hash table and a hash file is how you access the data. The actual hashing part remains the same throughout.

    I hate to keep bothering, but how do I deal with collissions now.

    I have set up a while loop to go through the entire file, and I read on record at a time and hash it. how can i deal with collissions within in my while loop???

    that will be the last of my questions!

    Since you are using linear probing you don't have to make any changes, handle collisions the same way: If your hashed index is already taken, move to the next one until you find an empty index.
