The order of constants can be explicitly
enum colors { black, | // | value | 0 |
red, | // | value | 1 |
green, | // | value | 2 |
blue=6, | // | value | 6 |
violet, | // | value | 7 |
white=4 }; | // | value | 4 |
Initializer expression can include previously declared enumerators. For example, in the following declaration:
enum memory_sizes { bit = 1, nibble = 4 * bit,
byte = 2 * nibble, kilobyte = 1024 * byte };
nibble would acquire the value 4, byte the value 8, and kilobyte the value 8192.
Anonymous Enum Type
In our previous declaration, the identifier colors is the optional enumeration tag that can be used in subsequent declarations of enumeration variables of type
colors:
enum colors bg, border; // declare variables bg and border
As with struct and union declarations, you can omit the tag if no further variables of this enum type are required:
/* Anonymous enum type: */
enum {black, red, green, blue, violet, white} color;
Enumeration Scope
Enumeration tags share the same name space as structure and union tags. Enumerators share the same name space as ordinary variable identifiers. For more information, consult Name Spaces.
