General section
Computer
science
general
c/c++ section
Java section
The question paper had 48 questions to be answered in
1hr. Time will be quite sufficient. They have different
sets of question papers. I had got the paper with serial
number ending with ***- 02-2003.
I would like to request everyone who have attended the
HP test to contribute the questions that they remember.
Some questions that i remember are...................
1>General section : computer science general knowledge
2>
Computer science general: simple questions
1) HP acquired this company in 2002. Which is the
company
a)Compaq b)Dell c)option 3 d) Option4
Ans: a
2) what does 3G denote
a) 3rd generation mobile communication b) 3rd generation
computer
languages c) option 3 d) option4
Ans: a
3)an
application
program
that is used by the users to get the inofrmation from
the backend of some application like databases:
a)
application
server
b)proxy server c)database server d)option 4
Ans: database server
4) which of the following is not true about the e-mail
a) it can be accessed by a client program using POP
b) it can be accessed by a client program using imap
protocol
c) option 3
d) option 4
Ans: I don't remember the answer but first 2 are true.
5) Some quesion regarding the company and who developed
it ( the thing to remember is that Apple produce
Macintosh computers).
5) What is X.25?
a)option 1 b)option 2 c)option 3 d)option 4
Ans: find out??:-)
3> c/c++ section: questions on c/c++, programs o/p etc.
1) main( )
{
unsigned int i=3;
while( i >=0)
printf( "%d", i--);
}
how many times will the printf stmt be executed?
a)0 b)3 c)4 d)infinite
Ans: I think the answer is infinite, b'cos 'i' is an
unsigned integer and it will not decrement below '0' and
hence end up in an infinite loop.(yes, i checked and it
is getting stuck in an infinite loop)
2) main( )
{
int x,y, z;
x=2;
y=5;
z= x+++y;
printf("%d %d %d", x, y z);
}
a)3 5 7 b)option 2 c)option 3 d)option 4
Ans: a
3) # define swap(a,b) temp=a; a=b; b=temp;
main( )
{
int i, j, temp;
i=5;
j=10;
temp=0;
if( i > j)
swap( i, j );
printf( "%d %d %d", i, j, temp);
}
Ans: On compiling i got ans 10, 0, 0. I did not
understand the concept. Please expalin this to me.
4>Java section: questions on java related stuff.
1) Java was initially code named as:
a)Oak b)green c)miller d)option4
Ans: Oak
2) what is not true about the following statements about
java.
a) it is compiled using javac compiler
b) the compiled files have .class extension.
c) such files cannot be transfered from one comp to
another.
d) they use the java interpreter
Ans: c
3) Why is the synchronize used?
a) to initialize multiple objects b)to lock an object
c)option3 d)option 4
Ans: b (probably)
HP paper 21 Oct 2003
there were 3 sections
PART- 1 --> 40 q's (Fundamental computer Concepts,
includes OS,N/w , protocols)
PART-2 --> 20 q's (Purely C ) -- bit tricky (involves
ADA concepts)
PART-3 --> 20 q's (Analytical) --- very easy
I don't remeber all the q's.however some of them which i
do have been written below.
They r not in order or part of .
Q : What is not a part of OS ?
O : swapper,compiler,device driver,file system.
A : compiler.
Q : what is the condition called when the CPU is busy
swapping in and out pages of
memory without doing any useful work ?
O : Dining philosopher's
problem,thrashing,racearound,option d
A: thrashing.
Q : How are the pages got into main memory from
secondary memory?
DMA, Interrupts,option3, option 4
A : as far as i know its Interrupts --by raising a page
fault exception.
Q : What is the use of Indexing ?
O : fast linear access, fast random access, sorting of
records , option 4
A : find out....
Q : in terms of both space and time which sorting is
effecient.(The question is
rephrased .)
O : merge sort, bubble sort, quick sort, option 4
A : find out
which case statement will be executed in the following
code ?
main()
{
int i =1;
switch(i)
{
i++;
case 1 : printf ("");
break;
case 2 : printf("");
break;
default : printf("");
break;
}
}
Answer : Case1 will only be executed.
Q : In the given structure how do you initialize the day
feild?
struct time {
char * day ;
int * mon ;
int * year ;
} * times;
Options : *(times).day, *(times->day), *times->*day.
Answer : *(times->day) -- after the execution of this
statement compiler generates
error.i didn't understand why.can anybody explain.
Q: The char has 1 byte boundary , short has 2 byte
boundary, int has 4 byte boundary.
what is the total no: of bytes consumed by the following
structure:
struct st {
char a ;
char b;
short c ;
int z[2] ;
char d ;
short f;
int q ;
}
Options are given.
Answer : its very easy 20 and not 19 .
HP Paper 15 Sep 2003
HP Q Paper Pattern:
48Q 1 hr
12Q General Knowledge
12Q General CSE
12Q C and C++
12Q Java
The q's r as follows:-
1. Which of the foll is not a protocol.
HTTP PIM PSI
A> PSI (check)
2> Which of the foll does not help security.
Good Password
Update Antivirus
VLAN
A> VLAN
3> What was the prob with Intel Processor
Cache
FPU
NONE
A> FIND OUT AND LET ME KNOW
Q.# define swap(a,b) temp=a; a=b; b=temp;
main( )
{
int i, j, temp;
i=5;
j=10;
temp=0;
if( i > j)
swap( i, j );
printf( "%d %d %d", i, j, temp);
}
Ans: On compiling i got ans 10, 0, 0. I did not
understand the concept. Please expalin this to me.
and...the answer fot ur question is
first preprocessor will modify ur code before
compilation...so
the #define swap will be substituted in the line no.6 of
the
main...so ur code will become like this before
compilation...
line 1: int i, j, temp;
line 2: i=5;
line 3: j=10;
line 4: temp=0;
line 5: if( i > j)
line 6: swap( i, j );
line 7: printf( "%d %d %d", i, j, temp);
because of preprocessor, line 6 becomes
temp=i; i=j; j=temp;
so...this is equivalent to
temp=i;
i=j;
j=temp;
hence...ur overall main becomes
int i, j, temp;
i=5;
j=10;
temp=0;
if( i > j)
temp=i;
i=j;
j=temp;
printf( "%d %d %d", i, j, temp);
and...now i think u will know why the answer was 10, 0,
0 ..
