Aric - Arithmetic coding utility

Seminar assignment from course Programming in C. Aim of this assignment is to make a program to compress and decompress arbitrary files using arithmetic coding.

Usage

usage: aric -c FILE COMPRESSED
       aric -d COMPRESSED FILE

To compress an input FILE to COMPRESSED output file use the flag -c. To decompress the COMPRESSED file back use the second option -d with output file FILE.

Example usage

Compress

./aric -c coder.c out.aric
    output: 3883 bytes to 2879 bytes

Decompress

./aric -d out.aric coder_decompressed.c
    output: 2878 bytes to 3883 bytes

Verify that the original file is identical to the decompressed file

if cmp -s coder.c coder_decompressed.c
then
    echo OK
else
    echo FAILED
fi
