I assume you mean, your posts get closed or downvoted? Yeah, that'll happen.
It's a case-by-case thing, so it's hard to say exactly why, but a large part of it stems from the fact that stack overflow is meant as the be-all and end-all "FAQ" encyclopedia kind of site. It's full of stuck-ups. :)
If you ask questions on ephemeral issues that only you are having, others won't see the value in these kinds of questions. As in, your question (and its answer) isn't adding to the library of collective knowledge that the site is trying to achieve.
But it could also be that you aren't doing things like giving a Minimal, Reproducible Example
. It's hard for others to help you with a runtime issue if they can't even compile your code. And, often, when you force yourself to produce a minimal reproducible example, it's likely you'll narrow down the issue on your own.
I don't think I've used their post wizard, but have you looked at https://stackoverflow.com/help/how-to-ask
? The advice in that article seems OK to me. I would also take a look at a random sampling of downvoted 'New' questions and upvoted 'Active' questions from the site's main page. Compare things in common with questions that get downvoted, and things in common with questions that get upvoted.
On the other hand, the users of this once-great forum don't have grandiose delusions of compiling the perfect C++ problem encyclopedia. The advice given in the above article can definitely still be applied here, and you should try to search for your question to see if it's a common/existing one, but the people here probably don't mind helping to solve one-off issues that probably only affect you. At worst, your question just won't be answered if nobody wants to trudge through it.
