ı am opened c++ character class but some gives error
Does your code compile successfully?
We haven’t heard from you in a few days, so I’m going to mark this question as resolved for tracking purposes. Feel free to open it up again if you are still encountering this issue.
On a side note about your question, though: 4.19 is known to have some issues with Visual Studio’s intellisense. Visual Assist can help a bit, but the main solution would be to upgrade to 4.20. With 4.20.3, a fix was added to which folders were set to be included in the generated project which fixes most, if not all, of the incorrect error “squiggles.”
