The answer is 16 (on most compilers), but not for the
reasons stated above.
If the class contained only c1 and c2, the size would be
2. Since i1 is an integer, though, it needs to be aligned
on a 4-byte multiple. The pointer and the other integer
also uses up 4 bytes. So, the total size is 16.
If there were another character field "c3" adjacent to c2,
the size would still be 16 bytes.
