Question

As per my knowledge, enum can be used like

typedef enum
{
   true,
   false,
   undefined    
}FLAGS;

true and false can be used like

int a = 1;
if(a == true)
   ....
else if(a == false)
   ....

Coming to my issue, I came across a enum usage like,

FLAGS Options[] = {true, undefined};

i.e array is declared of type enum. I have no idea. Please clarify me.

Edit:: What will happen in the mentioned scenario.

prinf(“\n true:%d, false:%d, undefined:%d\n”, true, false, undefined);

true: 0, false:1, undefined: 2

why?

Edit 2::
How it differs with int Options[] = {true, undefined};

An enum is just like an integer type, with the added bonus of having a bunch of named literals. There’s nothing stopping you from declaring an array of enumerated values, it’s basically just an array of integers.
