Write a program to create a hashed file, Data Structure & Algorithms

Assignment Help:

Write a program to create a hashed file that stores the records currently in the file "data_2013". Records should use the same fixed-length schema given previously, and should again be written in binary.

When inserting the records into your new file, they should be hashed on the ID attribute.

Using a static hashing approach, with the hash functionID % pageswhere pages is the number of pages in the file) to determine which "page" of the file the recordsshould be stored in. For simplicity (so that you do not need to worry about the possibility ofoverflow records), assume an average occupany of 80%. (Hint: as a first step, your programshould calculate the total number of pages that there will be in your file, based on the numberof records to be stored, the occupancy, and the pagesize parameter.) You should implement this hashing algorithm yourself.
