Creating an Enum element

To define the enum, we utilise the enum keyword.

The syntax for defining a union is as follows:

enum enum_name
{
    element1,
    element2,
    element3
};

Here’s an example of how to define and use a union as a user-defined data type in main.

enum Meal
{
    breakfast,
    lunch,
    dinner
};

Initialising and using enum elements

Because each enum member is assigned a value, they can be used to determine if two variables store the same value.

#include <iostream>
using namespace std;
 
enum Meal
{
    breakfast,
    lunch,
    dinner
};
 
int main()
{
    Meal m1 = dinner;
    if (m1 == 2)
    {
        cout << "The value of dinner is " << dinner << endl;
    }
}

Output:

The value of dinner is 2
