Depending on the size of the value, it might also change the size of the union. Anonymous unions are now more conformant to the standard. Previous versions of the compiler generated an explicit constructor and destructor for anonymous unions. These compiler-generated functions are deleted in ...
Previous example with anonymous union will look as follows:TYPEDEF_STRUCT (tree_node_t, ANON_UNION (value, __attribute__ ((packed))), (intptr_t, int_value), (double, dbl_value), (char *, str_value), (void *, ptr_value), END_ANON_UNION ("discriminator"), (struct tree_node_t ...

C++ supports anonymous unions (unions without names). This reduces the level of access operators that must be applied to access an element of a structure containing a union. struct VarData { int type; union { int integerData; float floatData; char charData; }; }; VarData d; d.integerDa...

An anonymous union is not a type; it defines an unnamed object and it cannot have member functions. The member names of an anonymous union must be distinct from other names within the scope in which the union is declared. You can use member names directly in the union scope without any...

You can declare and initialize a union in the same statement by assigning an expression enclosed in braces. The expression is evaluated and assigned to the first field of the union.ExampleКопіювати // using_a_union.cpp #include <stdio.h> union NumericType { int iValue; long...
