Is the
following code legal?
struct a
{
int x;
struct a *b;
}
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.
