Do not use namespace using directives?
Namespace usings are for your convenience, not for you to inflict on others: Never write a using declaration or a using directive before an #include directive.

What is name lookup?
Name lookup is the procedure by which a name, when encountered in a program, is associated with the declaration that introduced it.

Explanation: It is known that “std” (abbreviation for the standard) is a namespace whose members are used in the program. So the members of the “std” namespace are cout, cin, endl, etc. This namespace is present in the iostream.

Reverse IP address lookup converts the IP address number to the name. For most computer users, this process occurs behind the scenes.
Why is C++ still used?
