**Enumeration** allows for the creation and usage of a new data type with a defined set of constants that are available as values. The enumerators have a constant integer value ranging from 0 to N, unless specified otherwise. Enums can make the program more readable and easier to manipulate.

# Syntax
```C++
enum enumeration_name {enumerator1, enumerator2, ... };

//or
enum {enumerator1, enumerator2...};
```




# Explanation

The code below demonstrates two enumerators in practice. 

The first enumeration, named `languages`, contains commonly used programming languages. The compiler then, by default, assigns integer values to each of the languages, starting from 0. 

The illustration demonstrates the integer value assigned to each language. `my_variable` is initialized to `swift` after declaration. `my_variable` then prints out the integer value assigned to `swift`. 




Similarly, the second enumeration, named `data_structures`, contains seven elements. However, the first element has been assigned a value of 5, instead of the #key# default value :0 #key#. The succeeding elements take values after 5 until some other value is assigned. In this case, the 5th element is assigned a value of 3 and the following elements take up values after that, as shown in the illustration.

#include <iostream>
using namespace std;

int main()
{
    enum languages {C, go, python, swift, java};
    languages my_variable;
    my_variable = swift;
    cout<<"my variable: "<<my_variable<<endl;

    enum data_structures{array = 5, list, vectors, trees , graphs = 3, stacks, queues};

    cout<<array<<'\t'<<list<<'\t'<<vectors<<'\t'<<trees<<'\t'<<graphs<<'\t'<<stacks<<'\t'<<queues<<endl;

    return 0;
}

What are enumerated constants in C++?

Enumeration defines a new data type with specified constants, enhancing readability and manipulation in C++. Enum values are integers unless otherwise specified.
