Question

Assume that p and q are pointers. What will be the output after performing following sets of operations on a given linked list ?
struct node{
char data;
struct node *next;
};

Operations are
I. q=p→next→next;
II. p→next→next=q→next→next;
III. q→next→next→next→next=q→next;
IV. printf("%c", p→next→next→next→next→data);

1.    e
2.   f
3.    d
4. Segmentation fault

Comments

I think d will be output

---

it is option 3.

1) q = p->next->next = pointing to c

2) q->next->next = e

hence p->next->next = e (b->next =e)

3)q→next→next→next→next = f->next

f->next = q->next = d

now printf will be p→next→next→next→next→data => b→next→next→next→data => e→next→next→data

f→next→data => d→data => d
