Explanation / Answer

1.
A. Give the values of the following expression
1. ptr->info: 30.
2. ptr2->next->info: 90.
3. listdata->next->next->info: 45.

B. Are the following expressions true or false?
1. listdata->next == ptr1.   True.
2. ptr1->next->info == 60. False. It is 45.
3. listdata->info == 25 True.

C. Write one statement to do each of the following.
1. Make listdata point to the node containing 45.
listdata = ptr1->next;   //This will point to node with value 45.
2. Make ptr2 point to the last node in the list.
ptr2 = ptr2->next; //This will point to the last node in the list.
3. Make listdata point to an empty list.
listdata = NULL;   //listdata now point to NULL.
4. Set the info member of the node containing 45 to 60.
ptr1->next->info = 60; //ptr1->next->info is holding 45, and this statement updates its value to 60.
