SECTION III - ANALYSIS PROGRAM SEGMENTS

---------------------------------------

1) Here is the structure declaration of a doubly

linked list

struct dlink {

int nodeid;

struct dlink *next;

struct dlink *prev;

} dlink_t;

A pointer of the head of the linked list is maintained

as a global variable,

whose definition is

dlink_t *head;

The funtion remove_element(dlink_t *rp), needs to

remove the node pointed to

the rp and adjust the head.

The first node's prev and the last node's next are

NULL.

remove_element(dlink_t *rp)

rp->prev->next = rp->next;

rp->next->prev = rp->prev;

if( head == rp)

head = rp->next;

Which of the following statement is true about the

function remove_element

B) It does not work when rp is the last element on the

list

c) It sets the head of the list correctly

D) It works in all cases

Answer :B

2) Consider the following function written in c:

#define NULL 0

char *

index(sp,c)

The first argument sp, is a pointer to a C string. The

second

argument, c, is a character. This function scarches

for the character

c, in the string. If it is found a pointer to that

location is returned

else NULL is returned.

This function works

a) Always

character c

c) works when c is a non NULL character only

d) Works only when the character c is found in the

string

party consists

of at least two knights. The two parties travel by

separate routes,

northern and southern. After one month, the routes of

the northern

and southern groups converge for a brief time and at

that point the

parties before

continuing, again in two parties along separate

northern and southern

routes. Throughout the entire trip, the composition of

travelling

parties must be in accord with the following

exactly three

members, which of the following is not a possible

travelling party

and route?

a) P,S,U by the northern route

b) P,S,T by the northern route

c) P,S,T by the southern route

d) P,S,U by the southern route
