Enumeration in C

User defined data type

enum keyword

enum week {mon, tues, wed, thur, fri, sat, sun};

enum week day = wed;

//Here day is the variable of type week

//Value of day is = 2;

//value of mon = 0, tue = 1, and so on

We can initalize two enum names to same value.

If we don not explicitly initialize vlues to names, compiler will assign default values from 0.

ex: enum value { day1 = 19, day2, day3=91, day4}

Here compiler assign value of day2 = 20 and day4 = 92

enum exam{test, sample};

enum lab{sample, collect};

sample in two enums in same scope not allowed
