Size of structure with a char, a double, an int and a t [duplicate]

Answer 1

$9.2/12 states - "Nonstatic data members of a (non-union) class declared without an intervening access-specifier are allocated so that later members have higher addresses within a class object. The order of allocation of nonstatic data members separated by an access-specifier is unspecified (11.1). Implementation alignment requirements might cause two adjacent members not to be allocated immediately after each other; so might requirements for space for managing virtual functions (10.3) and virtual base classes (10.1)."

So just like the sizeof(double) and sizeof(int), the offsets at which structure members would be aligned is unspecified, except that members that are declared later are at higher addresses.
