Novell placement papers

The paper consists os three sections.
1. aptitude 15 questions 20 min.
2. system concepts 20 questions 20 min.
3. 'c' 15 questions 20 min.
I'm sendin the questions, many of them have no answers. U do check the
answers for all the given questions also.
All questions are MULTIPLE CHOICES ONLY.
U do try to cover the related topics to get some understanding.
In interview They are asking C C++ Operating system concepts
and Networks.
They will ask about Ur interesting subjects, U try to have good
grip on those intresting subjects.
They asked about c c++ project work and operating systems.
Don't worry, prepare well, get it, All the best.
section 1::::;
*. GRE book test paper 3 section 5
question no. 8 to 12 (ships WXYZ starting on dec. 23rd..........)
* 5 programs are sheduled from monday to saterday, monday is not holiday,
PQRST are the programs. Theday before P is holiday, and some other clues are
given, we have to find the sequence (4 questions)
ANS: tuesday is the holiday
P comes on wednesday ,
U can do the remaining very easily.
* Suppose U R the presoner, There are two guards Who will tell truth or
one will tell truth. There is a gate for liberty and another foe hell.
Some questions are given, like
i. are U tell truth?
ii. another tell truth or not??
iii. both of U R telling truth??
iV. both of U lieing??
V. --------------
they gave a. b. c. d. and asking about which sequencing is sufficient to
find the gate for liberty??
( I can't give exact thing)
* There are WIFE and HUSBAND at one side of river. They have one child,
They want to cross the river. The child can't be lonly. The boat boy won't
permit morethan one to cross the river, what is the correct way to
cross the river??
* There are 7 targets, A B and C has to shoot them. All should be shooted
1. The no. of chances for A and B are not less thn 2,
2. for C there is only one chance.
3. A can't shot 3 times consicutively.
4. B is permited to shoot in even chances only.
They have given some 3or 4 questions on this
section 2:
This part is System concepts(25 Q in 20 min).We haven't remember exactly, but it
will help alot if u spend some time to revise these concepts.

or the question is for fastest gate (EIL)
17.which of the following is the wrong statement

d)none ans : a
19.Which of the following reduces CPU burden
a)DMA b)............ ans :a
20.malloc function allocates memory at
a) compilation time b)link c)load d)running ans: d
section 3::
1.Max value of SIGNED int
a. b. c. d.
2.One questin is given, long one, to find the answer U should be
with the operation as follows
int *num={10,1,5,22,90};
int *p,*q;
int i;
print the value of i, and q-p, and some other operations are there.
how the values will change??
3. One pointer diff is given like this:
int *(*p[10])(char *, char*)
asked to find the meaning.
4. char *a[4]={"jaya","mahe","chandra","buchi"};
what is the value of sizeof(a)/sizeof(char *)
a. 4 b.bytes for char c-- d.--
( we don't know the answer)
5. void fn(int *a, int *b)
int *t;
int a=2;
int b=3;
print the values os a and b;
what is the output--- out put won't swap, the same values remain.
a. error at runtime
b. compilation error
c.2 3
d. 3 2
#define scanf "%s is a string"
what is the output.
ANS : %s is string is string
7. i=2+3,4>3,1;
ans is 5 only.
8. char *p="abc";
char *q="abc123";
print("%c %c",*p,*q);
a. aabbcc
b. aabbcc123
c. abcabc123
d. infinate loop ( this may be correct)
9. printf("%u",-1)
what is the value?
a. -1 b. 1 c. 65336 d. --
(maxint value-1 I think, check for the answer)
10. #define void int
int i=300;
void main(void)
int i=200;
int i=100;
print the value of i;
print the value of i
what is the output?
may be 100 200
int x=2;
printf("%d ",x);
int a[]={0,0X4,4,9}; /*some values are given*/
int i=2;
printf("%d %d",a[i],i[a]);
what is the value??? (may be error)
some other program is given , I can't remember it
U can get it afterwads,
the answer is 3 3, so U can check this in the exam. itself.
