Here is a silly programming language I created in 2006. Deadfish has only four commands: o for output accumulator, s for square the accumulator, d for decrement the accumulator and i for increment the accumulator. It's a long story about the name, it just came to me basically.
The Esolang Wiki was where Deadfish was born. I'm thankful that many eager programmers made other implementations of Deadfish. The file I host here is just the Python and C implementation of Deadfish, which are both by me. The C implementation is a bit different than the Python one, and it was implemented first.
Thanks goes out to: ais523,Oerjan Johansen and all other contributers!
