Why do we need enum in C?
Enumeration (or enum) is a user defined data type in C. It is mainly used to assign names to integral constants, the names make a program easy to read and maintain.
What are enumeration variable How are they declared what is the advantage of using them in a program?
Variables of enum type can be used in indexing expressions and as operands of all arithmetic and relational operators. Enumerations provide an alternative to the #define preprocessor directive with the advantages that the values can be generated for you and obey normal scoping rules.
What is significance of storage class which storage classes are in C explain static in context of functions and variables?
A storage class specifier in C language is used to define variables, functions, and parameters. auto is used for a local variable defined within a block or function. register is used to store the variable in CPU registers rather memory location for quick access. Static is used for both global and local variables.
What is a variable in C language?
A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in C has a specific type, which determines the size and layout of the variable’s memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable.
What is enum in TypeScript?
Enums are one of the few features TypeScript has which is not a type-level extension of JavaScript. Enums allow a developer to define a set of named constants. Using enums can make it easier to document intent, or create a set of distinct cases. TypeScript provides both numeric and string-based enums.

Why do we need enum in C#?

Can a variable have a name which is already in an enumeration?
No variable can have a name which is already in some enumeration: C++11 has introduced enum classes (also called scoped enumerations ), that makes enumerations both strongly typed and strongly scoped. Class enum doesn’t allow implicit conversion to int, and also doesn’t compare enumerators from different enumerations.
