Does Objective-C have enums?

Objective-C Language Enums Defining an enum You also can set your own raw-values to the enumeration types.

What is enum in Objective-C?

typedef enum declaration in Objective-C A enum declares a set of ordered values – the typedef just adds a handy name to this. The 1st element is 0 etc.

What is enum in C with example?

Enumeration or Enum in C is a special kind of data type defined by the user. It consists of constant integrals or integers that are given names by a user. The use of enum in C to name the integer values makes the entire program easy to learn, understand, and maintain by the same or even different programmer.

How are enums stored in C?

Enumeration “values” aren’t stored at all, as they are compile-time named constants. The compiler simply exchanges the use of an enumeration symbol, with the value of it.

What is typedef enum in Objective-C?

A typedef in Objective-C is exactly the same as a typedef in C. And an enum in Objective-C is exactly the same as an enum in C. This declares an enum with three constants kCircle = 0, kRectangle = 1 and kOblateSpheroid = 2, and gives the enum type the name ShapeType.

Why don’t we use strong for enum property in Objective-C?

We don’t use strong for enum property in Objective-C because enums aren’t objects so we can ‘t specify them as strong or weak.

What is typedef and enum in C?

A typedef is a mechanism for declaring an alternative name for a type. An enumerated type is an integer type with an associated set of symbolic constants representing the valid values of that type.

What is the size of enum in C?

The C standard specifies that enums are integers, but it does not specify the size. Once again, that is up to the people who write the compiler. On an 8-bit processor, enums can be 16-bits wide. On a 32-bit processor they can be 32-bits wide or more or less.

Why are enums 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.

What is enum in C stackoverflow?

@Solver: enum strategy { }; defines an enumerated type named enum strategy , where strategy is the tag. enum { } strategy; defines an anonymous enumerated type (no tag) and a single object of that type named strategy .
