(iii) enumeration type

1.enum Weekday{sum,mon,tue,wed,thu,fri,sat};

Declares an enum-type enum weekday, which can be used to define a variable. Such as:

Enum weekday workday,week_end;

Workday and week_end are defined as enumeration variables, and their values can only be sum to one of the SAT . Such as:

Workday = Mon;

Week_end = sum;

Equivalent to

enum {Sum,mon,tue,wed,thu,fri,sat} workday,week_end;

They are one of them.

2. Of course you can use

typedef enum {SUM,MON,TUE,WED,THU,FRI,SAT} weekday;

That is equivalent to enum WEEKDAY{SUM,MON,TUE,WED,THU,FRI,SAT};
