prifit he will gain on both.
5.five cities. city1 is west to city3.city4
is east to city 5._____etc.which is farthest
on west side.
6.one question on: =+,*=,/=* etc then
10/5*45=?
7.on ,C, paper is easy.mostly on pointers,3
question on structures,5 on fundamentals,
8.ex:define max 10
main()
{
int a,b;
int *p,*q;
a=10;b=19;
p=&(a+b);
q=&max;
} Q a)error in p=&(a+b) b)error in p=&max
c)error in both d) no error
important suggestions:
1. average preparation is enough to qualify
foe interview.time is enough.
2.they are particular about academic
background .
3.interview is only on personal details.no
question on technical subjects
4.they may change paper sets also.
5.in outside recruitment they are asking
more questions on CAD.
but not in campus.
in iitd they interviewed 5students out of 21
.selected 1,waiting list 1.
6.cut off cgpa:7.5
Optimize the below 1,2,3,4 questions for
time:
1)

if i=0 then i:=1;
if i=1 then i:=0;
2)
int i;
if i=0 then i:=1;
if i=1 then i:=0;
(given that i can take only two values
(1,0))
3)
int i;
if i=0 then i:=1;
else if i=1 then i:=0;
(given that i can take only two values
(1,0))
4)

for i:=1 to n do
m:=m+j*n
5) Expand the following

A,B,C,D depending on when
the errors are detected?
A if no error is detected

b) Undeclared identifier
c) stack underflow

sequence of pages when LRU
page replacement algorithm is used ( The
memory can only have 3pages):
1,2,3,4,2,1,5,2,4 (something like that)
8) If a CPU has 20 address lines but MMU
does'nt use two of them.
OS occupies 20K. No virtual memory is
supported. What is the
maximum memory available for a user program?
9) For a binary tree with n nodes, How many
nodes are there which
has got both a parent and a child?
10) Understand the funda of incrementing a
variable using
val++ and ++val . Some programs are given
for error correction.
11) Learn datagram . (Computer networks)
12) Which of the following can be zero?
(only one)
a) swap space
b) physical memory
c) virtual memory
13) What is a must for multitasking?
a) Process preemption
b) Paging
c) Virtual memory
d) None of the above
14) A question on call by value,
call by name,
call by reference.
f(x,y,z)
{
y := y+1;
z := z+x;
}
main()
{
int a,b;
a := 2
b := 2;
f(a+b,a,a);
print a;
}
what is the value of a printed for three
different calls in main.
15) Using the following instructions and two
registers , A&B.
find out A XOR B and put the result in A
PUSH <reg>
POP <reg>
NOR These instructions operates with A & B
and puts the result in
AND A
(question basically to get XOR in terms of
NOR and AND)
16) True/False questions:
1) The page size should be the power of 2.
2)
17)
int i=0;
int j=0;
loop:
if(i = 0)
i++;
i++;
j++;
if(j<= 25)
goto loop
xxx:
question1 : how many times is the loop
entered
A few questions of that sort. some count
fundaes. Easy one )
18) Who handles page faults?
a) OS
b) MMU
c) Hardware logic
d) etc etc....
19) For which of following is it not
possible to write an algorithm.
a) To find out 1026th prime number
b) To write program for NPcomplete problem
c) To write program which generates true
Random numbers.
etc...
20) what is the essential requirement for an
realtime systems
a) preemption
b) virtual memory
c) paging etc...
