11. Decide whether the syntax of each of the following statements is valid or invalid, if it is valid, mark it OK; if it is invalid, explain what is wrong. a. listData->next = ptr1->next; b. listData->next =*(ptr2->next); c. *listData = ptr2; d. ptr2 = ptr1->next->info; e. ptr1->info = ptr2->info; f. ptr2 = ptr2->next->next;

Solution

Serial#

Statement

Valid/Invalid

Reason

a.

listData->next = ptr1->next;

VALID.

RHS and LHS both are both NodePointers.

b.

listData->next =*(ptr2->next);

INVALID.

Cannot assign LinkNode to NodePointer.

c.

*listData = ptr2;

INVALID.

Cannot assign a NodePointer to a LinkNode.

d.

ptr2 = ptr1->next->info;

INVALID.

Cannot assign integer to a NodePointer.

e.

ptr1->info = ptr2->info;

VALID.

RHS and LHS both are both integers.

f

ptr2 = ptr2->next->next;

VALID

RHS and LHS both are both NodePointers.
