Enumerations
An enumeration data type is used for representing an abstract, discreet set of val-
ues with appropriate symbolic names.
Enumeration Declaration
Enumeration is declared like this:
enum tag { enumeration-list };
Here,
of discreet values, enumerators. The enumerators listed inside the braces are also
known as enumeration constants. Each is assigned a fixed integral value. In the
absence of explicit initializers, the first enumerator is set to zero, and each suc-
ceeding enumerator is set to one more than its predecessor.
Variables of
example, the following declaration
enum colors {black, red, green, blue, violet, white} c;
establishes a unique integral type,
enumerators with constant integer values (
variable of an enumerated type can be assigned any value of type
checking beyond that is enforced. That is:
c = red;
c = 1;
With explicit integral initializers, you can set one or more enumerators to specific
values. The initializer can be any expression yielding a positive or negative integer
value (after possible integer promotions). Any subsequent names without initializ-
ers will then increase by one. These values are usually unique, but duplicates are
legal.
