How to use enumerations in C/C++?

Enumeration is a user-defined data type in C language. It is used to give names to integer constants, making programs easier to read and maintain. The keyword "enum" is used to declare an enumeration.

The following is the syntax for enumerations 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{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\n\n",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;
