boost::asio::ip::tcp::socket mySocket;In this example, `boost::asio::ip::tcp` is the QualifiedName (library) and `socket` is the local name (class). The QualifiedName is used to avoid naming conflicts between classes/functions with the same name. By specifying the library/namespace, we can ensure that we are referring to the correct class/function. Determining the package/library can be done by looking at the list of namespaces or libraries included in the code. In the above examples, `std` is a namespace included in the standard C++ library, while `boost::asio::ip::tcp` is a namespace included in the Boost.Asio library.
