Answer :

Compiler Error

Explanation:

The structure yy is nested within structure xx.
Hence, the elements are of yy are to be accessed through the
instance of structure xx, which needs an instance of yy to
be known. If the instance is created after defining the
structure the compiler will not know about the instance
relative to xx. Hence for nested structure yy you have to
declare member.
