Hello,

Consider an 'empty' struct as follows:

struct Test {}

When printing it's size, it's always 1.
void main()
{
    writeln(Test.sizeof);
}

Output:
1

Why is it not 0?  What about struct Test is consuming 1 byte of memory?

Thanks,
Mike

Looks like this answers my question:

C++ exhibits the same behaviour for what is most likely the same reason: so that empty structs can be allocated without two distinct objects having the same memory address ( http://stackoverflow.com/questions/2362097/why-is-the-size-of-an-empty-class-in-c-not-zero )
