All mangled symbols begin with _Z (note that an identifier beginning with an underscore followed by a capital letter is a reserved identifier in C, so conflict with user identifiers is avoided); for nested names (including both namespaces and classes), this is followed by N, then a series of <length, id> pairs (the length being the length of ...
Unique Student Identifier logo. Unique Student Identifier (USI) is a unique educational reference number issued by the Australian Government to all higher education students (including universities, TAFEs and independent tertiary colleges) for the purpose of collecting information about a student's training and study activity, and their movements within the VET and higher education systems in ...
In C and C++, keywords and standard library identifiers are mostly lowercase. In the C standard library , abbreviated names are the most common (e.g. isalnum for a function testing whether a character is alphanumeric), while the C++ standard library often uses an underscore as a word separator (e.g. out_of_range ).
A namespace in computer science (sometimes also called a name scope) is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols (i.e. names). An identifier defined in a namespace is associated only with that namespace. The same identifier can be independently defined in multiple namespaces.
A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. [1] The concept was formalized early in the development of computer science and information systems. In general, it was associated with an atomic data type.
Universal identifiers represent various schemes used to uniquely reference people, companies, and other things across domains, systems and organizations. They are used mostly in computer systems and databases, and provide a way to find objects whose names may change.

A Universally Unique Identifier (UUID) is a 128-bit label used to uniquely identify objects in computer systems. The term Globally Unique Identifier (GUID) is also used, mostly in Microsoft systems. [1] [2] When generated according to the standard methods, UUIDs are, for practical purposes, unique.
