Files

Description

Write two programs to handle binary data:

• encode-data: Convert a file of comma-separated data into a binary encoded file.
• read-data: Print a specific range of records from a binary encoded file created by the encode-data program.

For this assignment, we will use the following dataset: Pokémon for Data Mining and Machine Learning. You are allowed to hard-code assumptions based on this data. A modified copy of the data is on the Linux server here: /export/home/public/schwesin/cpsc552/data/

General Specifications

• The default make target should create both executables.

• Your programs must all be properly modular and documented appropriately.

• Each program must use a different family of functions for file I/O. That is, one program must use file descriptors and the other program FILE pointers. You can choose which program uses which method.

encode-data Specifications

• The name of the compiled program must be encode-data.

• The input to the program must be in the form of command line arguments as follows:

  • -h (by itself with no other arguments) print the usage instructions
  • -i <string> (required) the input CSV file
  • -o <string> (required) the output binary file

  Note that the command line arguments must be able to be entered in any arbitrary order,

read-data Specifications

• The name of the compiled program must be read-data.

• The input to the program must be in the form of command line arguments as follows:

  • -h (by itself with no other arguments) print the usage instructions
  • -f <string> (required) the input binary file
  • -n <integer> (required) the first record in the range
  • -m <integer> (required) the last record in the range

  Note that the command line arguments must be able to be entered in any arbitrary order.

• Write the records in a well-labeled, human readable format.

• A given record should be accessed with a seek; only one record may be in memory at a time.

Turning in the Assignment

For this assignment, you must turn in a zip file of a directory named project1 containing the appropriate files.

Submit the zip file to the appropriate folder on D2L.
