A structure specifier indicates an aggregate type consisting of a sequence of named members.
A union specifier defines a type whose members begin at offset zero from the beginning of the
union.

Description
A structure is a named collection of members. Each member belongs to a name space
associated with the structure. Members in different structures can have the same names but
represent different objects.
