Huffman again!
Hi there,
I have done the implementation of huffman code but i have a difficulty compressing .exe files:
1.The uncompressed file is different than the original file and thus doesn't work properly.(The size of the files are the same, just they function differently.)
2.The compression is not actually a compression since the size of the file not only does not decrease (in exe files or large file in general) but also gets bigger.
I want to know has anybody in this forum done and implementation of this coding method?if so please give your resaults and the compression ratio.
regards,
Capitan Haddock

Ok, so you got some problems with your encoding or decoding. Run the program on some small data (just a few bytes) which you can verify by hand.

What? You definately got some big problems.

I wrote one in C++, but that was more than 10 years ago, so I can't remember, but it was usually pretty good, but it depends on the data.
