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).
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.

Interview Details:
i gone through 3 interviews, two technical and one hr first is on project,os, unix, networks, micro processor, c, software engineering second on micro processor,c, software engineering and some general hr is just for formal to give offer letter.
First Interview
first question is as usual, tell me about yourself. They observe your expressions and way of your delivary and your confidence. Friends be confident while you are telling, my suggesstion is prepare beforegoing there on paper and practice yourself before mirror.
Then they ask about your project. They sometimes going in detail and ask you, while doing your project , in which areas you feel tough and how would you overcome yourself. They made me to write some important functions related to my project and i have been explained their prototypes. Be thorough in your project.
in my project socket progrmming is there and they asked me in depth in inter process communications like semaphores, shared memory. i am unable to answer most of questions. The questions i remembered are ,
which is fastest ipc and why. semaphores.for reason please go through some books like Unix system programming by batch. a program is given with 100 lines of code and another program also with 100 lines of code, both have to executed and first program with 50 lines first then second has to be started and after second finishses it s 50 lines first process has to be started. which inter process communication you use?
Ans: Semaphore with wait and signal operations
Some questions on operating systems like cpu scheduling, what are types of scheduling in priority scheduling , how can we increase priority of a process
Ans: using nice command in unix we can
Coming to Networks
TCP/IP reference model they asked me then at which layer which device would be there.
Ans: internet layer router
Transport layer host host to network layer switches, repeters. then they asked me where would be bridges i said they on datalink layer and is part of host to network layer. then question is, is bridge is software or hardware i said of both then question is , can we have bridge with only software then i said, i am not sure, but now days bridges are almost absent and routers are doing the functionality of them. then they asked me some questions on ip addressing
Size of IPV4 address 4 bytes
Sizeof Ipv6 address 16 bytes
Size of mac address 48 bit
Then they shifted to C and questions are below
What happens if malloc falis to allocate memory
Would program continue or abort
Ans: i tell we can check it s return value by malloc, if it fails returs null and we can do our required action.
//program on sizeof operator
void main()
{
char *s[10]={"welcome","to","india"};
printf("%d",sizeof(s));
}
ans:10*sizeof(char*)
it is 10*4=40 under unix
it is 10*2=20 under turbo c++ compiler
//program that analyses about constant
void main()
{
const int i=10;
int *p;
p=&i;
(*p)++;
printf("\n %d",i);
return;
}
would it execute
Ans: it is going to be and we get 11.

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).
6) What is X.25?
a) option

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( )

b)
green
c)
miller
d) option4
Ans: Oak
2) What is not true about the following statements about java.

{
int i=1;
swith(i)
{
i++;
case 1: printf("case1");
break;
case 2: printf("case 2");
break;

Interview Details:
i gone through 3 interviews, two technical and one hr first is on project,os, unix, networks, micro processor, c, software engineering second on micro processor,c, software engineering and some general hr is just for formal to give offer letter.
First Interview
first question is as usual, tell me about yourself. They observe your expressions and way of your delivary and your confidence. Friends be confident while you are telling, my suggesstion is prepare beforegoing there on paper and practice yourself before mirror.
Then they ask about your project. They sometimes going in detail and ask you, while doing your project , in which areas you feel tough and how would you overcome yourself. They made me to write some important functions related to my project and i have been explained their prototypes. Be thorough in your project.
