What is the difference between enum and array?
The main difference is that an array is a value and an enum is a type. And One main difference we can say that an array is a collection of other values (that is it contains other values, you can iterate through them or access individual ones by index), whereas an enum value is simply one atomic value.
What is enumerated data type 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 is the difference between an array and a struct?
A structure creates a data type that can be used to group items of possibly different types into a single type. Array refers to a collection consisting of elements of homogeneous data type. Structure refers to a collection consisting of elements of heterogeneous data type. Bit filed is not possible in an Array.
What is enumerated datatype in OOP?
An enumerated type declares an optional type name and a set of zero or more identifiers that can be used as values of the type. Each enumerator is a constant whose type is the enumeration. For example, if you are creating an application that has a fixed number of types for some variable.
What is enum variable?
An enum type is a special data type that enables for a variable to be a set of predefined constants. The variable must be equal to one of the values that have been predefined for it. Because they are constants, the names of an enum type’s fields are in uppercase letters.
What is an enum value?
In computer programming, an enumerated type (also called enumeration, enum, or factor in the R programming language, and a categorical variable in statistics) is a data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type.
What is array in C program?
An array is defined as the collection of similar type of data items stored at contiguous memory locations. Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc.
What are enumerated types used for?
You should use enum types any time you need to represent a fixed set of constants. That includes natural enum types such as the planets in our solar system and data sets where you know all possible values at compile time—for example, the choices on a menu, command line flags, and so on.
What are the main differences between array and collection?
Java
| Arrays | Collection |
|---|---|
| Arrays are fixed in size that is once we create an array we can not increased or decreased based on our requirement. | Collection are growable in nature that is based on our requirement. We can increase or decrease of size. |
What is the difference between array and Pointer in C?
Array in C is used to store elements of same types whereas Pointers are address varibles which stores the address of a variable. assignment array variable cannot be assigned address of another variable but pointer can take it.
What are enumerated data types with example?
An enumerated type is a type whose legal values consist of a fixed set of constants. Common examples include compass directions, which take the values North, South, East and West and days of the week, which take the values Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday.
What is an enumerated list?
An enumeration is a complete, ordered listing of all the items in a collection. The term is commonly used in mathematics and computer science to refer to a listing of all of the elements of a set.
