Placement Papers - HCL

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. 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 min time. So that you can answer each and every section very carefully.. ok

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

10) Traverse the given tree using in order, Preorder and Post order traversals.
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
",*&*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
",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.
