@#53890 I think whatever default rules we got for taking input would be ok to use too. (more) |

Technically, a macro parameter is not a global and equivalent to passing a function parameter by reference, and the result of a macro should be equivalent to `return`. So I think this is fine - usually typing out `#define` for a function-like macro isn't ideal for golfing, but sometimes it is. (more) |

A: Single letter HTML [C (gcc)], 31 30 bytes #define f(a) strchr("abipq",a) Try it online! f(a){return strchr("abipq",a);} The most obvious (and non-creative) solution. This under default rules that a truthy value in the language is anything non-zero. To display explicitly 1 or ... (more) |

@#53890 Ok in this case I must use another named parameter so I don't think that would improve golfing. I'll add the return. (more) |

@#53890 Huh I might have mixed up several rules with each other. Well in that case I suppose I should add a return statement. (more) |

A: Lone ones [C (gcc)], 67 bytes a;r;i;f(long n){for(;i<33;)a=n&1l<<i++?a?2:1:a&1?r++,0:0;return a;} Try it online! General algorithm: - This is a little state machine where the variable 'alone' `a` can have the value 0=zero, 1=alone candidate, 2=not alone. Essentially a 'carry' but ... (more) |

I think the point here is whether or not it is ok to take input as a string rather than an integer. With default rules I believe that should be just fine. (more) |

@#53890 Heh, thanks. I think it's simply because I was used at writing everything as a one-liner and forgot obvious things :) Saved only 3 bytes though because one was apparently a tab. (more) |

@#53890 It depends on the language. Many languages block execution if there are serious compiler diagnostics ("errors"). Other languages like C and C++ do not. The important part here is that the program must run. But as usual each solution would compete against other solutions with a similar app... (more) |

It doesn't really matter that much, it's just an offset of fixed number of characters that you add/remove to the total. But it's quite far-fetched (at least in the C family of languages) to say that input and output to a program may come through function parameters IMO, which I believe are the de... (more) |

Category migration and the sandbox This has probably been discussed before but I couldn't find any posts about it. I think we should re-make the sandbox category in the following way: - Votes in the sandbox category should not count towards user reputation. If users get intimidated to post sandbox proposals fearing down-vo... (more) |

Source with the whole alphabet in order of appearance The challenge is to write as short a source as possible, where the English alphabet (in alphabetical order from top to bottom) `"abcdefghijklmnopqrstuvwxyz"` is a sub-sequence of the source code. The first mentioning of the next expected letter is the only one that counts. If a letter appears... (more) |

A: How many odd digits? [C (gcc)], 41 bytes r;o(chars){for(;s;r+=s++&1);return r;} Try it online! This is under the assumption that in a function solution, input has to be passed as parameter and output through the return value. The result variable is allocated outside the function to get gcc implic... (more) |

@#53890 I honestly have no idea but probably all of the mainstream ones. Perhaps less so esoteric languages? The challenge accepts answers which is "language x + library y" even if "y" isn't officially part of the language/standard but some common extension. Like for example one could post an ans...
