This is a slightly modified piece of coursework that I did a decade ago. I've changed it to keep up with changes to the C programming language and compiler etc over the years. The task was to write a file compression program in C that used two compression techniques. I chose run length encoding because it was easy to do, and Huffman coding because it was a bit more tricky and so would be an interesting challenge.

To build it on Linux, type make. It has various tests, run these using make test
