chuffman

huffman coding implemented in C for educational purpose from scratch.

Using Encoding Tree and Decoding Tree to achieve information Compression and Extraction.

The code works well with ASCII texts.

usage

$gcc *.c -o chuffman -Wall

$./chuffman

for huffman encoding

$./chuffman -e book.txt -b codebook.txt -o encoded.txt

you can also use

$./chuffman -e book.txt

but the default filename of codebook is codebook.txt

the default filename of encoded file is output.txt

for huffman decoding

$./chuffman -d encoded.txt -b codebook.txt -o origin.txt

you can also use

$./chuffman -d encoded.txt

but the default filename of codebook is codebook.txt

the default filename of decoded file is output.txt

Example

here is an example about compiling the code and using it to encode and decode file 'example/book.txt'.
