SECTION A

The following program accepts a pair of 2 numbers from the user of system and totals them. Numbers are accepted in pair repeatedly and totaled, until grand total of all the pair of numbers accepted does not exceed 9.
Step 1 : Assign value 0 to x
Step 2 : Accept 1st number and assign to A
Step 3 : Accept 2nd number and assign to B Freshersworld.com
Step 4 : Add A and B assign to C
Step 5 : Add C to X
Step 6 : If X<10 go to Step 1
Step 7 : Stop.
The error in the above routine is
Step 6 should be If X<9 go to Step 1
Step 1 is redundant
Step 4 should be Add A & B and assign to X
Step 6 should read If x<10 go to Step 2
Step 1 should be Assign value 0 to A & B

The following program finds the greatest of the three numbers A, B and C and prints the result
Step 1 : If A>B assign A to X
Step 2 : If A>C assign A to X
Step 3 : If B>C assign B to X Freshersworld.com
Step 4 : Print X
The error in the above program:
It does not work in case C > A
It does not work in case B > A
It does not work in case C > B
It does not work in case A = B = C
All of the above
Study the following program and answer the following questions :
Step 1 : A = 0
Step 2 : B = 0
Step 3 : If B > 1
Step 4 : A = A + 1
Step 5 : B = B + 1
Step 6 : GOTO 7
Step 7 : END IF 9 Freshersworld.com
Step 8 : B = B - 1
Step 9 : Stop.

In written test in each section you have to get minimum marks
i.e you have to pass in each section. There will be questions
from C, C++, JAVA. about 10 questions in C++ in the written test.

HCL

HCL PAPER ON 26th NOVEMBER AT CHENNAI

Hi... Friends Bhaskar reddy here.. I was attended for HCL Technologies in Anna University on nov 26th and I got placed. Here I am presenting my experience in written test and interview. I hope it may be useful for you…

Written test consists of 4 sections. In each section we have to get minimum marks. Which means it’s a sectional cut off. Also negative marking is there. They will deduct ¼ of each wrong answer... Ok... You just answer all questions with lot of confidence...ok

They will give all 4 sections question paper at a time… so you can start any section.

Total paper consists of 65 Questions and provided 90 mini times. So that you can answer each and every section very carefully… ok

SECTION-I :( Microprocessor (8086only) +Networks+operatingsystems+Fundamentals of computers)

This section consists of 15 Questions. Here I remember some questions……

1) Non Maskable Interrupt is a…..

a) NMI
b) Software interrupts
c) Hardware interrupts
d) Software and hardware interrupt

Ans: b

2) Which of the following is error correction and deduction?

Given tree:

Ø Inorder : D H B E A F C I G J

Ø Preorder: A B D H E C F G I J

Ø Postorder: H D E B F I J G C A

And some more questions….. I dint remember those questions

Given tree:

Ø Inorder : D H B E A F C I G J

Ø Preorder: A B D H E C F G I J

Ø Postorder: H D E B F I J G C A

And some more questions….. I dint remember those questions

SECTION –II (C language Basics and programming) this section consists of 20 Questions…….. All are programs only…

1. main()

{

printf("%x",-1<<4);

}
a) fff0
b) fffb
c) ff0
d) none
Ans: a
Explanation: -1 is internally represented as all 1's. When left shifted four times the least significant 4 bits are filled with 0's.The %x format
specifier specifies that the integer value be printed as a hexadecimal value.

2. main()

{

char *p;

p="Hello";

printf("%c\n",*&*p);

}

a) e

b) H
c) some address
d) ome garbage value

Ans: b

Explanation: * is a dereference operator & is a reference operator. They can be applied any number of times provided it is meaningful. Here
p points to the first character in the string "Hello". *p dereferences it and so its value is H. Again & references it to an address and * dereferences it to the value H.

3. void main()

{

int i=5;

printf("%d",i++ + ++i);

}

a) 11

b) 12

c) 10

d) output cant be predicted

Ans: d

Explanation: Side effects are involved in the evaluation of i

4. main( )

{

int a[2][3][2] = {{{2,4},{7,8},{3,4}},{{2,2},{2,3},{3,4}}};

printf(“%u %u %u %d \n”,a+1,*a+1,**a+1,***a+1);

}

a) 100, 100, 100, 2

b) 101,101,101,2

c) 114,104,102,3

d) none

Ans: c

Explanation:The given array is a 3-D one. It can also be viewed as a 1-D array.

100 102 104 106 108 110 112 114 116 118 120 122

thus, for the first printf statement a, *a, **a give address of first element . since the indirection ***a gives the value. Hence, the first line of the output.for the second printf a+1 increases in the third dimension thus points to value at 114, *a+1 increments in second dimension thus points to 104, **a +1 increments the first dimension thus points to 102 and ***a+1 first gets the value at first location and then increments it by 1. Hence, the output is C is correct answer…

5. main( )

{

static int a[ ] = {0,1,2,3,4};

int *p[ ] = {a,a+1,a+2,a+3,a+4};

Hi...my Technical interview held like this..

Intwr: Hi, I am Mahesh butt

Me: hi sir I am bhaskarreddy

Intwr: ok.. Which project u did in your curriculum?

Me: sir my project is steganography

Intwr: oh... What is steganography?Why you choose this project? What’s your project purpose?

What is encryption?How you embedded the selection of sector? Which code u used?Which algorithm you used? Can you explain me?

Mostly I answered all questions.. Also he gave me paper and pen... Like that I explained to him very clearly with diagrams.

Intwr: So bhaskar u knows C well? You are good at C language?

(Because I wrote C and .NET in my resume)

Me: no... Sir, I am not proficient in C, but logically I am good and I am in intermediate stage.

Intwr: oh..ok… What is your area of interest?

Me: Digital Electronics… sir

Intwr: Are you sure?

Me: yes sir…(With lot of confidence)

Intwr:

A0

B0

\

c=1

A1

B1

Bhaskar you use your entire Digital electronics, but I Want inside circuit which always shows the output as 1.

The conditions are,

When x=0: A when condition is true , output is 1

When x=1: A>B When condition is false , output is 0

Consider A=A0A1

Consider B= B0B1

Here he given the time of 15 mini to solve above problem…. But I did it with in 5 mini with logic gates.

Then he asked me to explain the entire circuit?

I explained to him……….

Ok.. Bhaskar I am giving one more 15 mini time to solve above question…. But this time you have to do with Multiplexers….

Yes.. here I designed the circuit and I explained to him…. Here I impressed him a lot..

Intwr: Ok.. Good…. Draw the block diagram of Feed back amplifier?

Me: I drawn the diagram

Intwr: You just add forward and reverse bias diodes to the feedback? I did it… ok.. will this circuit runs

Me: Yes…. Sir

Intwr: why

Me: No sir

Intwr: why

Me: Bcz some nose occurs in output and said some thing..

Intwr: What is pointer?

What is data sturucture?

What is stack?Queue?

Explain the Doubly linked list program?

I explained to him very clearly…

Intwr:

main()

{

int *j;

{

int i=10;

j=&i;

}

printf("%d",*j);

printf(“%d”, j);

}

What is the output?

Me: I did it correctly

Intrwr: Write a program for Fibonacci series? But I want to print only last value?

Me: I wrote program for Fibonacci series.. But I don’t know how to print last value…

Intwr: are you shivering

Me: yes... Sir...

Intwr: why bhaskar.. You are good at your subject why cant you do this???

Me: I tried it.. at last I got it

Intwr: Ok bhaskar.. Now you can go…….

Me: Sir... Am I fit for HCL?

Intwr: Bhaskar lets see your dreams comes true

Me: Thank you sir…

After some time they called me to HR round.. That time only I decided that I cleared technical round..

HR: Hi... I am priya

Me: I am Bhaskar Reddy

HR: Tell me some thing about you?

Why you joined in Bhajarang?

In which domain you will work?

And some more simple questions?

So after that she gave me offer letter… so that was the great exciting moment in my life…

So friends don’t ever loose your hopes.. Keep on trying.. Surely one good day is waiting for you.. Till then you do hard work… ok.. Hard work never fails… GOOD LUCK
