Why An Empty Structure will occupy 2bytes of memory in C++
Theoretically an empty 'thing' shouldn't take any memory but then again, both
an empty 'thing' and a non-empty 'thing' could both start at the same memory
address which is forbidden by the C++ Standard. i.e.

Expand|Select|Wrap|Line Numbers
  1. if (&x == &y) // x and y are supposed to be the same object
  2.  
Alignment reasons might cause that the minimum address difference could or
would be equal to two (2). Don't worry about it.

kind regards,

Jos
