@#53588 Oh I misunderstood it then. Means I can easily shave this down some more. (more) |

@#53588 No idea what you mean. The task is to print a string "true" or "false". (more) |

Headers would have given it away, it was already quite easy 🙂 The answer is C or C++. Compiles with gcc default settings. C++ does not need iso646.h I believe. (more) |

@#8046 I think the most sensible implementation would be that each community can decide which categories that should use rep or not. Meta being one (perhaps set to no rep by default?), another example is sandbox categories like here on Code Golf. (more) |

@#54114 If you post it under Code Review, there doesn't need to be a specific problem to solve. Rather you are expected to post complete & working code. If you are extra curious about for example portability or performance or style etc you can mention it in the question though, as that tells reviewer... (more) |

@#53501 Except it is listed as C (clang). And with the new scoreboard system, it bumps away all solutions that _are_ actually C (clang). (more) |

@#54114 In this case you should add the function/function-like macro used. Otherwise anyone can just use the "`M` library" from my example for any single challenge. (more) |

Couldn't we have Codidact-specific challenges. Recreating the [Mathematics logo](https://codidact.com/community-assets/math/logo-large.png) sounds like fun but tricky challenge. (more) |

@Monica Cellio Isn't the issue here rather that the various metas shouldn't count rep of the main site. The posts proposed here would sit on meta. Other than that, I don't have any problem personally with giving a lot of rep to someone who makes the effort to draft up these rules in detail per langua... (more) |

There's a lot of issues with the library - most notably you should never define functions inside header files. I'd recommend to post it for Code Review at https://software.codidact.com/categories/44 (more) |

I posted a solution too, just for reference. Would this challenge be interesting in other languages too? (more) |

Curious to see how this turns out. Wasn't sure if I should restrict it to 15 or go with 100. The snippets would turn rather long in that case. Is this challenge sensible in a lot of different languages? The language won't need a line number counting feature, though it probably helps. (more) |

CD is an abbreviation for Codidact now? :( Aargh... I'm allergic to strange abbreviations. Especially of the kind that are already taken by Compact Disc. (more) |

You need to specify if these strings are taken as program input or if they can be constants. For example in C, you can merge two string literals by just typing `"ABC" "DEF"`. But to merge strings taken as input in run-time, it turns much more intricate. (more) |

@trichoplax. This one already went live [here](https://codegolf.codidact.com/posts/279820). And we still need a way to formalize moving things from sandbox to live challenge... guess I should mark it as "finalized" like some people do. As for the link, Roman numbers should be common knowledge really.... (more) |

@Hakerh400 Ok. I have a feeling overall that these requirements would rule out a lot of languages, why I never posted it. (more) |

Curious to know how if the 26 line requirement holds in plenty enough different languages or if too many languages enforces either stand-alone symbol-only lines, or non-alphabetic order (for example VB `Private Sub... End` wouldn't work since that language enforces line feed formatting with `End` on ... (more) |

"We can't currently vary properties of post types per category" This is strange though. The various metas shouldn't give rep IMO and that's a much bigger issue than the sandbox category on some sites. (more) |

I think test cases (such as examples of input/output) should not only be encouraged but mandatory. An example snippet of a non-golfed version in some common programming language is encouraged, as discussed [here](https://codegolf.codidact.com/posts/279635). (more) |

Amusingly, this is "Y macros", not "X macros"... because X didn't sit well with Roman numerals. I got trouble in one version of the code that used `X(10,X)` :) (more) |

I went ahead and proposed a [move post between different categories feature request](https://meta.codidact.com/questions/279815). It would be generally handy to have, I think. (more) |

Great idea. Although... is there a point in archiving old, finalized sandbox posts? Otherwise I believe that the best solution would make it possible for the poster move the post between categories, from sandbox to live challenges. (more) |

However, chasing down a specific poorly-specified program output to a certain compiler, system + options could perhaps be an interesting and very different challenge. If you write a program that purposely does something bad, resulting in crazy results, then task people to find a system and compiler t... (more) |

| Comment | Post #279755 |
A problem with your example is that can only be reproduced with a non-standard compiler for that language. So you would have to specify to what extent non-standard language extensions are allowed and if your program relies on them... which in turn would be a major spoiler. Running `main;` on a confor...

@Quintec†That's a l (L). And yeah the reason that l and 1 look identical on some fonts is the reason why one shouldn't name identifiers like that. (more) |

Isn't it a big problem that the robbers can just "brute force" it with trail & error by trying online compilers until they find a match? (more) |

And yeah `(int){8<88}<<8` can be rewritten as `1<<8` or `u'\xff'+!!u'\xff'` as `u'\xff'+1` but I'm saving the 1 for a rainy day. (more) |

If snippets are ok, what about necessary libs to make the snippet run? That is, to access some language features I would strictly speaking have to include/import etc a lib. (more) |

| Comment | Post #279679 |
Oh, and `t` actually doesn't have to be char. So with gcc implicit int abuse, this should be possible: `t;f(char*s){s[1]?f(s+1):0;for(t=*s;s[1];*++s=t)*s=s[1];}`. (more) |
— | over 3 years ago |
| Comment | Post #279679 |
Also, switching `while` with `for` will save you lots. `for(char t=*s;s[1];*++s=t;)*s=s[1];` should work. So how about this? `f(char*s){s[1]?f(s+1):0;for(char t=*s;s[1];*++s=t)*s=s[1];}`, 59 bytes. (more) |
— | over 3 years ago |
| Comment | Post #279679 |
I think this might be a possible improvement: `f(char*s){s[1]?f(s+1):0;while(s[1]){char t=*s;*s=s[1];*++s=t;}}}`. In case s[1] is a character, it makes the recursive call and then while loop. If not, a `0;` dummy statement. `s[1]` is zero in that case so the while loop isn't executed. (more) |

Probably a good idea. If the OP makes an attempt to write the non-golfed version of the challenge, then they'll realize various requirements that need to be addressed. (more) |

How can you say that it relies on non-standard extensions while lecturing me about the standard at the same time? It's either, not both at once. (more) |

| Comment | Post #279415 |
I think this is kind of cheating since that online compiler declares a main() elsewhere. Otherwise you could improve it to `m(){m();}`, 9 bytes, a recursive call that will eventually stack overflow with seg fault (more) |

| Comment | Post #279383 |
Nice solution since it's quite straight-forward, +1. I managed 108 bytes with same compiler settings (default gcc) but a much more obscure solution [here](https://codegolf.codidact.com/a/279365/279534). (more) |

Then maybe the Q&A category needs to be "seeded" with some example questions so that people understand what it's for. The current help for categories and FAQ on this site isn't helpful. (more) |

But essentially they are lying just to pose and feel good about themselves. If you post an ill-formed, non-conforming program in "language X", that also relies on non-standard extensions, you are actually not programming in language X but in something else. That gives them an unfair advantage to thos... (more) |

| Comment | Post #279408 |
This sounds reasonable enough, especially if help files can get kept up to date to match community consensus on meta. Maybe "code-golf-rules" or "challenge-rules" are better tag names though? Since standards might be confused with formal language standards. (more) |
