printbf VS color-flood-for-amstrad-cpc

Somewhat related to this, printf alone in a loop is Turing-complete, by using %-directives like that. It was introduced in “Control-Flow Bending: On the Effectiveness of Control-Flow Integrity” (Carlini, et al. 2015) and the authors have implemented Brainfuck and an obfuscated tic-tac-toe with it.

No shit, you can write a brainfuck interpretter in printf statements: https://github.com/HexHive/printbf

well this is a brainfuck interpreter inside printf. I’m pretty sure there are plenty of c-to-bf transpilers.

const int myarray[mysize];

* Good news: C can do compile time constant structs and array with deep self-references.

Yes, in C you can define and fully declare complex data structures that are accepted as compile-time constants, including pointers to parts of itself.

See "self-contained, statically allocated, totally const data structure with backward and forward references (pointers)?" for a previous example at https://stackoverflow.com/questions/47037701/can-c-syntax-de...

-----------------

I used this for a game on a retro machine where such a data structure avoids code which would have been several times (perhaps 10 times) bigger: https://github.com/cpcitor/color-flood-for-amstrad-cpc/blob/...

Here's another take showing two variant: where overall construct is an array then a struct: https://gist.github.com/fidergo-stephane-gourichon/792c194e1...
