/*question number 5*/
Code:
struct node *nPtr, *sPtr; /* pointers for a linked list. */
for (nPtr=sPtr; nPtr; nPtr=nPtr->next)
{
free(nPtr);
}Choice 1
It will work correctly since the for loop covers the entire list.
Choice 2
It may fail since each node "nPtr" is freed before its next address can be accessed.
Choice 3
In the for loop, the assignment "nPtr=nPtr->next" should be changed to "nPtr=nPtr.next".
Choice 4
This is invalid syntax for freeing memory.
Choice 5
The loop will never end.
