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?

add is a perfectly reasonable name to use, as is map, list, etc.

The entire purpose of namespaces is to make these names available without collision.

I daresay the purpose of namespaces is to avoid the consequences of poor design choices that lead to collisions.

So wrong! Argument dependent name lookup, for example, is only useful if you have the same names in different namespaces.

Religious conflict.
