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

9) Consider the following prg
void funca (int *k)
{
*k += 20
}
void funcb (int *x)
{
int m=*x,*n = &m;
*n+=10;
}

Occurs and Causes available in http://www.simplyfreshers.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.
