When I installed doom emacs, I added lsp, c and c++ support and other things to init.el. When I started writing code in C, after adding the header file, auto completion advised me to add a comment to the code and other strange things. What could this be related to?
I can’t speak for C but I know Python has a similar thing in PEP8, to add comments at the top of a file. So lsp will show that as an error/warning.
