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
A) It work when head is the same as rp
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)
register char *sp,c;
{
do {
if(*sp == c)
return (sp);
} while (*sp++);
return NULL;
}
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
b) Always, but fails when the first byte contais the
character c
c) works when c is a non NULL character only
d) Works only when the character c is found in the
string
answer: a

Occurs and Causes available in placement papers.com
Six knights - P,Q,R,S,T and U - assemble for a long
journey in two
travelling parties. For security, each travelling
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
knights can, if they wish, rearrange their travelling
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
conditions
P and R are deadly enemies and, although they may meet
briefly,
can never travel together.
p must travel in the same party with s
Q cann't travel by the southern route
U cann't change routes
16) If one of the two parties of knights consists of P
and U and
two other knights and travels by the southern route,
the other members
of this party besides P and U must be
a) Q and S
b) Q and T
c) R and S
d) R and T
e) S and T
answer: e
17) If each of the two parties of knights consists of
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
e) Q,R,T by the southern route
ans: b
18) If one of the two parties of knights consists of U
and two other
knights and travels by the northern route, the other
memnbers of this party
besides U must be
a) P and S
b) P and T
c) Q and R
d) Q and T
e) R and T
answer: c
19) If each of the two parties of knights consists of
exactly three
members of different parties, and R travels by the
northern route,
then T must travel by the
a) southern route with P and S
b) southern route with Q and R
c) southern route with R and U
d) northern route with Q and R
e) northern route with R and U
answer: a
20) If, when the two parties of knights encounter one
another after
a month, exactly one knight changes from one
travelling party to the
other travelling party, that knight must be
a) P
b) Q
c) R
