section 1
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?

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 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

knights and travels by the southern route, the other members of this party
besides P and U must be

c) southern route with R and U
d) northern route with Q and R
e) northern route with R and U

1.HCL has two divisions
a)
technology division
b) application division.
if
a student opts for
a)
then
he has to give 2 papers
b)
1) aptitude(25
questions)
c)
2)technical(30
approx).if he opts for 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 technology students are given
another test of 15 minutes in which they have to write a C program(reversing
string, reversing singly/doubly link list(FAVOURITE))and then interview is
taken.
3.if you have good command in comp s then opt for technology paper.
4.in apti(for tech people) if you do 8-10 out of 25 then it is on safe
side.
