Enum in C
Enumeration is a user defined datatype in C language. It is used to assign names to the integral constants which makes a program easy to read and maintain. The keyword “enum” is used to declare an enumeration.
Here is the syntax of enum in C language,
enum enum_name{const1, const2, ....... };The enum keyword is also used to define the variables of enum type. There are two ways to define the variables of enum type as follows.
enum week{sunday, monday, tuesday, wednesday, thursday, friday, saturday};
enum week day;Here is an example of enum in C language,
Example
#include<stdio.h>
enum week{Mon=10, Tue, Wed, Thur, Fri=10, Sat=16, Sun};
enum day{Mond, Tues, Wedn, Thurs, Frid=18, Satu=11, Sund};
int main() {
printf("The value of enum week: %d\t%d\t%d\t%d\t%d\t%d\t%d
",Mon , Tue, Wed, Thur, Fri, Sat, Sun);
printf("The default value of enum day: %d\t%d\t%d\t%d\t%d\t%d\t%d",Mond , Tues, Wedn, Thurs, Frid, Satu, Sund);
return 0;
}Output
The value of enum week: 10111213101617 The default value of enum day: 0123181112
In the above program, two enums are declared as week and day outside the main() function. In the main() function, the values of enum elements are printed.
enum week{Mon=10, Tue, Wed, Thur, Fri=10, Sat=16, Sun};
enum day{Mond, Tues, Wedn, Thurs, Frid=18, Satu=11, Sund};
int main() {
printf("The value of enum week: %d\t%d\t%d\t%d\t%d\t%d\t%d
",Mon , Tue, Wed, Thur, Fri, Sat, Sun);
printf("The default value of enum day: %d\t%d\t%d\t%d\t%d\t%d\t%d",Mond , Tues, Wedn, Thurs, Frid, Satu, Sund);
}
