What is the correct syntax of enum?

In C programming, an enumeration type (also called enum) is a data type that consists of integral constants. To define enums, the enum keyword is used. enum flag const1, const2, ..., constN; By default, const1 is 0, const2 is 1 and so on.

What is enum with example?

What is typecasting in C?

Typecasting is converting one data type into another one. It is also called as data conversion or type conversion. It is one of the important concepts introduced in 'C' programming. 'C' programming provides two types of type casting operations: ... Explicit type casting.

What is enum used?

Enums are used when we know all possible values at compile time, such as choices on a menu, rounding modes, command line flags, etc. It is not necessary that the set of constants in an enum type stay fixed for all time. In Java (from 1.5), enums are represented using enum data type.

How do you create an enum?

An enum can, just like a class , have attributes and methods. The only difference is that enum constants are public , static and final (unchangeable - cannot be overridden). An enum cannot be used to create objects, and it cannot extend other classes (but it can implement interfaces).

How do you declare an enum in SQL?

An ENUM is a string object with a value chosen from a list of permitted values that are enumerated explicitly in the column specification at table creation time. See Section 11.3. 1, “String Data Type Syntax” for ENUM type syntax and length limits.
