Hey @Konstantin8105 and the others, thanks for improving c2go so much that it even builds now!
knightstour.c has been implemented by 2 friends and me for a university assignment.
It's about (as the name says :P) the Knight's Tour problem.
The first option uses the position (1,1) (1-indexed) and lets you choose a board size.
The second options lets you chose both the starting position and the board size.
The third option lets you chose both, and the knight tries to make a closed tour (info on that in the wiki article).
You can compare the transpiled version with the original C one.
knightstour.c is compiled with gcc main.c -o out -O3 --std=c99 -lm -Wall -Werror.
Verifying that the output is right is relatively easy, just follow the step numbers like a knight would/could:

Dear @carstenhag , please wait little bit for transpilation, because 2 PR are on review.
Could you prepare some tests in according to gcc version

commented on August 23, 2024
I'm not quite sure what you mean with "prepare some tests in according to gcc version", but I've just compiled the c program on gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) on ubuntu and "gcc"/clang on macOS:

commented on August 23, 2024
Ooh sorry, I forgot that. Option 1, Board Size (x): 8, Board Size (y): 8 should find a solution almost instantly. In general, open solutions with board sizes below 20x20 should be almost-instant (application is memory-bottlenecked at very large sizes)

Dear @elliotchance , @carstenhag ,
In according to present version of c2go, test case of knightstour.c is good.
Results of Go and C is not identical, because (in my point of view) different algorithm of sorting.
Feel free for comments.
(We can close that issue).
