An enumeration is a set of values called as elements, members, etc. This is essential when we carried out the operation with the limited set of values available for variable. For example – you can think of the days of the month can only be one of the seven days – Sun, Mon, Tue, Wed, Thur, Fri, Sat.<\/p>\n\n\n\n
The enumeration is declared using the enum<\/strong> keyword, followed by the comma-separated list of the valid identifiers. This list is enclosed within the curly braces {}. The syntax is given below.<\/p>\n\n\n\n Syntax –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Here, the enum_name denotes the enum type name and list of the identifiers enclosed within the curly bracket.<\/p>\n\n\n\n Each of the identifier in the enumeration list has its index position. The index of the first enumeration is 0; the second enumeration is 1, and so on.<\/p>\n\n\n\n Example –<\/strong><\/p>\n\n\n\n Let’s define an enumeration for months of the year.<\/a><\/a><\/a><\/p>\n\n\n\n Let’s say programming example –<\/p>\n\n\n\n Example –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n Example – 2<\/strong><\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n An enumeration is a set of values called as elements, members, etc. This is essential when we carried out the operation with the limited set of values available for variable.
