[LCP]struct size - Empty class size

[ritesh kala]

If the size would be 0 then creating an array of any number of such structs
would also result in size 0 and all of them would have the same address.
For example:
empty a[100] would result in a[0] and a[1] to have the same address.

This discussion about struct size is remiding me of one question I had...
What is the size of an emply class...

#include <iostream.h>
class empty
{
};

main()
{
    cout << "The size of empty class is " << sizeof(empty);
}


Out put:
--------

The size of empty class is 1

Can somebody explain me this behaviour....
