Answer / susie
Answer :
Yes.
Explanation:
*b is a pointer to type struct a and so is legal. The
compiler knows, the size of the pointer to a structure even
before the size of the structure
is determined(as you know the pointer to any type is of same
size). This type of structures is known as
‘self-referencing’ structure.
