In this section there are mainly questions based on C language like
find the errors in the program and what is the output of the following program.
some question i remember are
1) int i=10;
printf("%d %d %d",i++,i++,i--);
there is one or two more question on increment operator
2) Two question on redirection operator(>>)
3) int i=10;
if(1,i++,++i)
printf("The value for i is %d",i);
4) one question on structure and u have to fine the error in the syntax
5) int a=10,b=33;
a=a^b;
b=a^b;
a=a^b;
printf("%d %d", a,b);
6) int *a;
int (*b)();
printf("%d %d",sizeof(a),sizeof(b);
7) # define SQR(a) (a*a)
void main()
{
printf("%d", SQR(5));
}
8) And in another question # define directive is declared in the main() function of the program and u have to predict the output of the program.?
9) what is the time complexity of bubble sort (Ans: O(n^2))
10) what is the preorder traversal of the folowing tree
some tree is given (this is not the actual tree given in the paper only idea)
A
/ \
B C
/ \
D E
/ \
F G
11) x=2,y=6,z=6
x=y==z;
printf(%d",x)
12) What is the size of the address bus and data bus in 8086?
13) address of IVT in 8086?
Section II:
1) some 6 guys are there A,B,C,D,E,F(say) and u have to adjust in the row.
and some statements are there like A & D can't be adjacent
E,A have one vacant area in between.. like that and there are 5 questions are based on that?
2) this one is tricky .. there are two groups . one is many brothers can mary one sister of other group. and second is many sister can mary one brother of other group
and some statements are there like V & U is father of S, X is the only grandmother of S ...like that..
And there are 6 question based on that..
3) and rest of questions are purely aptitude & quant based.
like there are two questions on coding if MYSORE is code like MEMEME
then how TAMILNADU is coded?
HCL (or) HCL Perot Systems (HPS) (or) HCL-CISCO

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 fution
remove_element

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

c) R and S
d) R and T
e) S and T
ans: 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

application field then he
has
to give only
apti paper which is same as that of techni
paper.
2.after the written results are declared the
