They have some restrictions as opposed to traditional unions: in C11, they must be a member of another structure or union, [2] and in C++, they can not have methods or access specifiers. Simply omitting the class-name portion of the syntax does not make a union an anonymous union.
A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers private, protected or public.
One advanced dialect of C, called Cyclone, has extensive built-in support for tagged unions. [1] The enum types in the Rust, Haxe, and Swift languages also work as tagged unions. The variant library from the Boost C++ Libraries demonstrated it was possible to implement a safe tagged union as a library in C++, visitable using function objects.
The current method for workers to form a union in a particular workplace in the United States is a sign-up, and then an election process. In that, a petition or an authorization card with the signatures of at least 30% of the employees requesting a union is submitted to the National Labor Relations Board (NLRB), who then verifies and orders a secret ballot election.
It evaluates to the offset (in bytes) of a given member within a struct or union type, an expression of type size_t. The offsetof() macro takes two parameters, the first being a structure or union name, and the second being the name of a subobject of the structure/union that is not a bit field. It cannot be described as a C prototype. [1]
“Four-hundred thousand workers are now in a union that were not in a union when (Biden) became president.” Fact check: Union membership has increased under Biden, but still not at pre-2020 ...

The above rules also apply to all the base classes and to all non-static data members in the class hierarchy; It has no base classes of the same type as the first defined non-static data member; A class/struct/union is considered POD if it is trivial, standard-layout, and all of its non-static data members and base classes are PODs.
