head is a pointer to the head of a linked list of points that is built. How do you access
the member x of the head node of the list?

 struct point{
int x,y;
};
typedef struct point Point;
struct ptlist{
Point pt;
struct ptlist* next;
};
struct plist *head;

 A. head >pt >x
B. head >pt.x
C. Both are equivalent
D. Both are incorrect
Answer. B)
A pointer to a structure lets access to the member variables using “ >” operator and a normal
variable lets access through the “.” operator.
