Kshema Technical Test Questions

1. What are the key differences between C & C++.

2. How is the struct functionality different in C and in 
C++.

3. What is the difference between the following

a. i=i+1;
b. ++i;

ANS: ++i is a single instruction while in i=i+1, first i+1 
is computed and
then assigned.

4. What is the difference between the two files.

file1.c

# include...........

int i;

void main()
{

..........
}

file2.c

# include

static int i;

void main()
{
.....
}


ANS: While in this case for both the programs... the scope 
and lifetime of
variable 'i' is throughout the program..... the value 
of 'i' is not.
For eg. if 'i=2' in the file1.c, any other program 
accessing this
variable from outside will still see the value of i as 2.
Whereas in File2.c if the variable 'i' is accessed from any 
other
program its value will always be seen as 0

Reason: For static variables their values are active only 
within the
COMPILE AREA of where it is declared or in the program 
where it is declared.

4. Explain the OSI layer and TCP/IP layer and their 
differences.

5. Explain the difference in memory management in Windows 
and Linux if there
are any.

6. What are the differences between C++ in windows and C++ 
in Linux.

7. Explain some api's used in Networking (in LINUX and 
WINDOWS)

8. What is exception handling and how is it different from 
error
handling...... Why is exception handling used instead of 
error handling in
some cases and vice versa.

9. What is Hashing in Datastructures and why is it used. 
What the criteris
for Hashing and explain some of them.

10. What are the criterias to be considered for Searching 
algorithms.

ANS: The size of the list and whether it is sorted.(these 
two are apparently
most important.... and that is the answer they expect)

11. What is the key aspect of Object Oriented Programming

ANS: DATA ABSTRACTION (I personally felt "data 
encapsulation"...... but
apparently the former mentioned was and is correct)

12. Explain sliding window protocol.

13. What is the SELECT() API in networking. 


1.difference between C / C++

2.Explanation of OOP principles
-Data Abstraction.
-Data Encapsulation
-Inheritence
-Polymorphism
-Dynamic Binding.
-Reduction of Errors.

3.What is a Friend Function ? Explain with an Example.

4.Is the following code an Example of Dynamic Binding 
Explain?

class Base
{
Public:
virtual Bool Dosomething()
------
------
------
};

class Derived1: public Base
{
Public:
Bool Dosomething();
-----------
-----------
-----------
};

class Derived2: public Base
{
Public:
Bool Dosomething();
-----------
-----------
-----------
};

void main()
{
Derived1 derived1;
Derived2 derived2;

::process(derived1);
::process(derived2);
}

::Process(Base& Object)
{
Object.Dosomething();
}

Answer: In the processfunction above the downcasting is 
done while passing
parameters and in the function body upcasting is done so
object.dosomething() will be dynamic binding ( i am unable 
to explain the
answer in clear terms....but the line of thinking is 
something like
that....)

5.What will happen if in the above code in the base class 
the keyword
virtual is removed?

Answer: IF virtual is removed from the function 
declaration. when the
process function is called it calls the Dosomething 
function of the
Baseclass itself rather than the derived classes.

6.What is a circular queue? Why is it better than a normal 
queue? and Give
some practical Examples of usage of circular queue

Usage:
Scheduling Processes&Resources (esp in Operating Systems.)
used as a circular buffer especially in Embedded Systems
(because memory
is a constraint).

7.What is Hashing? Explain the procedure to obtain a 
hashing table.

8.Give a brief presentation of your 8th Semester Project.

i have joined this wonderfull group recently.and i thank all

i have information regarding the test in kshema technologies

i have written the test for kshema technologies
whoever are going to write written test of that 
company,dont panic

the test is easy to get thru

it consists of english,aptitude,and some c program segments 
thats all and its a simple paper .duration of test -1hr.and 
there will be 60 questions,out of which to qualify u need 
to get 60 % that is 36 questions

verbal ,depends on your ability

i suggest to go thru barrens,let us c
