Enum(s) and Memory

How does an enumerated data type use memory?
let's say i have

enum Family { brother, sister, mom, dad };

then i define it

Family intermediate;

How much space is set aside for intermediate?

And what's the difference/advantage of an enumerated data type and a whole bunch of ints?

>How much space is set aside for intermediate?

Code:

---

cout<< sizeof intermediate <<endl;

>And what's the difference/advantage of an enumerated data type and a whole bunch of ints?
An enumeration is more restrictive and provides more protection as a result. It also acts as documentation better than a "whole bunch of ints".

it says 4.. does this mean 4 bytes. type long?

>does this mean 4 bytes.
Yes.

>type long?
Does it matter?

Jeeze!! prelude!
