Which algorithm is used to compress a file ?

hello guy's
I have written some codes of huffman coading algorithm(lossles compression) in c.
And now i want to know which algorithm is used in populer compressed file like zip,rar,tar etc ?
Please provide some link where i can get moer detail about that algorithm.

    Are you trying to compress an image or what? There are many lossless compressions like zip, gzip, bzip2, lzma, etc... 😀

    no i don't have much idea about how lossy compression.I written a code using c to compress a text file.But i think my code is not an optimal code.So i want to know which algorithm is used in real time applications.
    Can you tell me which algorithm is used by these real time applications ?

    In real time they use LZMA compression algorithm. It is open source so, you can get the source code and implement... 😀
