Compiler for a simple esoteric programming language, in particular the minimalistic programming language Brainf***.
Brainf*** was developed by Urban Müller as a hypothetical programming language, and it is Turing-complete. It relies on pointers and memory management, which is perfect for a C project.
To run, download this C file and run cat test1.bf | ./a.out on your Unix-based/Unix-like terminal.
