Is it permissible to use short code snippets from the hints provided by the code author when I am confused while working on a problem and seek guidance?
Permitted by who and for what?
Is it for certificate projects?
I would suggest you create a forum post and ask for help. You will likely learn a lot more by asking for help than by copying code.
To course of each subject I study, and I extract code snippets from the given instructions
I’m still not sure I understand.
But unless code is licensed in a way that doesn’t allow for its use there is nothing stopping you from using it.
