What is the use of enum in C give an example?

The keyword ‘enum’ is used to declare new enumeration types in C and C++. Following is an example of enum declaration. In the above example, we declared “day” as the variable and the value of “Wed” is allocated to day, which is 2. So as a result, 2 is printed.

What is the type of enum in C?

In Enum, if we do not assign the values to the enum names, then the compiler will automatically assign the default value to the enum names. But, in the case of macro, the values need to be explicitly assigned. The type of enum in C is an integer, but the type of macro can be of any type.

What are enumeration variables 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.

Where do we use enum variable in C?

Enumeration is a user defined datatype in C language. It is used to assign names to the integral constants which makes a program easy to read and maintain. The keyword “enum” is used to declare an enumeration.

When would an enum or enumeration be used?

Whenever a procedure accepts a limited set of variables, consider using an enumeration. Enumerations make for clearer and more readable code, particularly when meaningful names are used. The benefits of using enumerations include: Reduces errors caused by transposing or mistyping numbers.

How do enums work C++?

Enum is a user-defined data type that consists of a fixed set of constants or we can say a set of integral constants. The enum keyword is used to define an enumeration in the C++ programming language. It can be used to represent a set of directions and days as enum are implicitly final and static.

What is the point of enums?

The entire point of enums are to make your code more readable. They are not casted to ints, since they are by default ints. The only difference is instead of going back and forth checking what int values you may have, you can have a clear set of enums to make the code more readable.

What is the use of extern in C?

Extern is a keyword in C programming language which is used to declare a global variable that is a variable without any memory assigned to it. It is used to declare variables and functions in header files. Extern can be used access variables across C files.
