こんぺこ〜こんぺこ〜こんぺこ!
I heard that Pico Pi @Raspberry_Pi only has MicroPython REPL at the moment, so I had some fun writing a brainf**k REPL in C++17 for Pico Pi XDDDDD (btw, the output image is also written in bf lang!)
The brainf**k interpreter is adapted from a previous project, you can find it in this post, Brainfuck Interpreter in C++17——A Modern Approach to Kill Your Brain.
