Example 4:
Compressing and decoding a file.

This example also demonstrates a nice feature of the AutoDecoder:

If you query a description after the decoding, the object tells you which combination has been used for encoding the input.

#include <LEDA/coding/coder_util.h>
#include <LEDA/coding/compression.h>

using namespace leda;

typedef CoderPipe2<MD5SumCoder, HuffmanCoder> Coder;

int main()
{
        Coder coder("foo", "bar");
        coder.encode();
        if (coder.fail()) std::cout << "error encoding foo" << "\n";

        AutoDecoder auto("bar", "foo");
        auto.decode();
        if (auto.fail()) std::cout << "error decoding bar" << "\n";

        std::cout << "Decoding info: " << auto.get_description() << "\n";

        return 0;
}
