Question

For questions 9 through, assume the SNode declaration given above, and the following code fragment SNodep new SNode (12) SNode qnew SNode (5) Hint: draw the resulting memory layout. 9. Which of the following expressions has the value 52 1) 2) q->Element 3) Next->Element 4) q-Next 5) 6) p->Element 7) p->Next->Element 8) p->Next 9) None of these 10. Which of the following expressions has the value 12? 1) q-Next 2) q-Next->Element 3) p->Element 4) 5) 6) p->Next->Element 1 and 3 only 2 and 3 only 7) 8) 9) and 4 only 2 and 4 only None of these Which of the following expressions has the value NULL? 5) None of these l) 2) 3) q-Next 4) q->Next->Next Pp 12. Again assume the SNode declaration above, and the following code, which builds a linked list with the numbers 18 and 32 as its components, has a missing statement. What should that statement be? SNode* pi SNode* q p new SNode (18, NULL) q-new SNode (32, NULL) /IStatement is missing here 2) p->Next new SNode: 3) p->Next # q; 4) p->Next-q->Next; 5) g P->Next; 6) None of these

Explanation / Answer

Q 9.  

2. q->Element

Q 10.

6. 2 and 3 only (because p->Element is 12 and since p is the next node of q ,so q->Next->Element is also 12)

Q 11.

4. q->Next->Next (because q->Next is p whose next is NULL )

Q 12.
3. p->Next = q; (becuase for a linked list, p should point to its next node which is q here,so we have to set p's next as q)
