// Constants:-
enum{stop, reverse, forward};

// Variables:-
int direction;

void setup()
{
    Serial.begin(115200);
    direction = reverse;         // direction now equals 1
    Serial.print(direction);
}

void loop(){}

More info:- enum

Yep. The members are numbered 0,1,2.....

When declaring the enum, it can also have a name like this:-

enum directions{stop, reverse, forward};

And you can set a value within the enum like this:-

enum directions{stop=1, reverse, forward};

Now the members are numbered 1,2,3

Or:-

enum{stop, reverse, forward=10, up, down};

And now the values are 0,1,10,11,12
