Q: std::array polymorphism

Tom HuntingtonIs this a sensible thing to do to get modern c++ features? Maybe I should just use std::vector template <typename T, unsigned N> struct polymorphic_std_array : std::array<T, N>, std::span<T> { polymorphic_std_array(std::array<T,N> a) : std::array<T, N>(a) , std::span<T>(*stati...

Q: Hidden html elements after search click

JRRSimply i should hide areas of my template after search click and return to its original state with the cleaning of the input related to each button.

As soon as you start to have other operators or many tokens in between the ? and then : like (, ), ., … and the expression between ? and : or after the : get really long it is hard to see what belongs to the ternary, and what isn't. And that is horrible for code reviews and maintainability. — t.niese 31 secs ago
No @OlivierRogier, asking for code to be rewritten in a different style is off-topic for Code Review. That site is only for reviewing finished code. — Toby Speight 21 secs ago

@TobySpeight Sometimes refactoring, beyond a simple concept, espacially large code, is better posted on codereview because stackoverflow is for problem solving: Is it appropriate to ask for help refactoring or simplifying code?Olivier Rogier 23 secs ago
@OlivierRogier Do not conflate something being off-topic on Stack Overflow as making the thing on-topic elsewhere. This question, which you have suggested be posted on Code Review, should not be posted on Code Review. — Peilonrayz 59 secs ago
@TobySpeight This question is closed for needs details or clarity, not "off-topic", as we don't really know what function(s) is expected and how it should be organized (too wide and opinion-based for me). The OP should edit and improve it to show the way to help. I suggested CodeReview because I think this question as-is is more than a writing question and has no value on StackOverflow. — Olivier Rogier 47 secs ago
This question needs to be improved for it to be reopened on Stack Overflow. When the refactoring is done, it could be a good idea to ask for review of the finished program on Code Review. It's a good idea to read A guide to Code Review for Stack Overflow users before posting your first review request, as some things are done differently over there - e.g. question titles should simply say what the code does, as the question is always, "How can I improve this?". — Toby Speight just now

Q: Preprocessing invalid xml before feeding it to a parser

apple1417As part of a larger project I'm writing to learn C++, I'm trying to read through some almost-XML files generated by another program.

@CaptainObvious I couldn't determine whether this is working code, or an off-topic "fix it for me".
1:48 PM
The code example you have provided is not a minimal reproducible example. In this code example there is absolutely no need to use CALL at all. I really don't think inappropriate is the word you want to use. Maybe you are looking for the best or most efficient way to solve your problem. Regardless the question is off topic because it does not provide a problem or error that needs fixing. If you want opinions on making your code better then post on CodeReviewSquashman 37 secs ago
Before you post at Code Review, make sure to read A guide to Code Review for Stack Overflow users, as some things are done differently over there - e.g. question titles should simply say what the code does, as the question is always, "How can I improve this?". Be sure that the code works correctly; include your unit tests if possible. You'll likely get some suggestions on making it more efficient, easier to read, and better tested. — Toby Speight 49 secs ago
