What does it mean by polluting the namespace?

yeah, I got that. but in my opinion, compiler is smart enough to understand whether a variable is declared in namespace std or not and using the namespace std out of the main function or beside each command will not make that much difference. I mean the necessary thing is to have this expression in your code

I think, they mean that if we use namespace std before each command, it helps compiler to use namespace for that specific statement that we have in our code (avoid using all the character that we have in the namespace std)
