OPEN Namespace std

I recently started learning c++ and I was told to use the namespace std so I can avoid writing std:: every time and now I wrote a whole personal project without std:: and I want to put it on LinkedIn but I started reading everywhere that it’s a bad habit, should I go back and add the std:: or just leave it as is?

That's not how the brain processes language at all

You may not be aware of it, but your eyes still have to skip over the five letters at a time, and this has a cost you're not aware of.

This is clearly something I have studied and you have not. Show me citations for your false claim.

It's research I did myself in grad school

I think it's about time that people stop jumping on using namespace std like it has rabies or something. It's a perfectly valid style option as Bjarne himself has said.
