Preparation

Preparation:

For C,C++--> Test ur C,C++ skills by Yashvanth kanithakar
For Java--> any good book.
Pattern:
48Q totally
12Q in General computer test?(Concentrate more on ceo's and founders of HP,Microsoft,intel,sap etc..)It even includes Q in OS,N/wing
12Q on C,
12Q on C++
12Q n java
All section r compulsory..(Even for Non java guys)

In the interview( ie ont he 2nd ropund..they will ask Q mostly in C,C++,Java.The employee who r asking the Q r very jovia
l.So develop ur confidence level.They mostly ask abt ur latest projects,
If u clear this level..next will be HR round.
If u clear the second round mostly..u r selected(90%).
HR is just for a formality..
The interview pattern will be as:
1. Tell abt your self.
2. They will ask for the subjects in which we are strong
( Here they will consider the ranking that we written during written
examination & marks we got in written exam)
3. Mostly the interview time will be 45 minutes around (for only
people there is about 1.5 hr)
4. HR questions may include here
5. Good thing is They r friendly and cooperative so confidence place
role.
If u don't know the answer better not to answer than to tell some bad
stuff.
For me 2 people interviewd. As I told them that I am strong in C
they told me to write some programs like double linked list, singly
linked list(adding node at last), macros, const *,char *,pointer
arrays.
The main question that they asked was how can u compile or
execute 'c' program without editor. (Using TCC utility)
coming 2 cpp only 1 question i.e what is polymorphism.
Java they asked me about protocol used in JSP, which layer does it
belongs to, main differences between _Javascript ,java and JSP.
During personal introduction try to excell your capabilities by
giving examples like as fast learner, hard worker like..!
If u have any achievements & awards try 2 put them all during
personal INtroduction.
The interviewers are very co-operative and highly friendly (so
confidence plays vital role)

Hi friends,
.There were 48 questions.There were 3 series of quesn
papers.
So prepare in general dont rely on the quesns that iam
going to send.
12 questions in each section
1> General IT information(easy)
2> C/C++ (very easy)
3> Computer Concepts(Database,Unix,....)
4> Java/JdBC (little tough)


The test comprises of 4 sections:
Section A. ------50qns(general appitude,english etc):
Section B. ------ 10 Questions on Computer concepts.
Section C. ------ 30 Questions on C
Duration 90min, no negative marking. one mark per question .
Once this is cleared then u must take a c programming test duration 40min.
5 programs,each got differnet papers.one i got was
1.WAP find and replace a character in a string.
2.WA function to perform the substraction of two .
Eg:char N1="123",N2="478",N3=-355(N1-N2).
3.WAP dynamically intialize a 2 dimentional array Eg:5x20,accept strings and check for vowels and display the no.finally free the space allocated .
4.WAP read a line from file from location N1 to N2 using command line agruments
Eg:exe 10 20 a.c freshersworld.com
5.WAP find the largest of 4 no using macros.


Some questions that i remember are...................

unsigned int i=3; freshersworld.com
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);

The distance between Station Atena and Station Barcena is 90 miles. A train starts from Atena towards Barcena. A bird starts at the same time from Barcena straight towards the moving train. On reaching the train, it instantaneously turns back and returns to Barcena. The bird makes these journeys from Barcena to the train and back to Barcena continuously till the train reaches Barcena. The bird finally returns to Barcena and rests. Calculate the total distance in miles the bird travels in the following two cases:
(a) The bird flies at 90 miles per hour and the speed of the train is 60 miles per hour.
(b) the bird flies at 60 miles per hour and the speed of the train is 90 miles per hour

A rich merchant had collected many gold coins. He did not want anybody to know about them. One day, his wife asked, "How many gold coins do we have?" After pausing a moment, he replied, "Well! If I divide the coins into two unequal numbers, then 37 times the difference between the two numbers equals the difference between the squares of the two numbers." The wife looked puzzled. Can you help the merchant's wife by finding out how many gold R

It was vacation time, and so I decided to visit my cousin's home. What a grand time we had! In the mornings, we both would go for a jog. The evenings were spent on the tennis court. Tiring as these activities were, we could manage only one per day, i.e., either we went for a jog or played tennis each day. There were days when we felt lazy and stayed home all day long. Now, there were 12 mornings when we did nothing, 18 evenings when we stayed at home, and a total of 14 days when we jogged or played tennis. For how many days did I stay at my cousin's place?

How many nails does the carpenter use?


Answer and Explanation.

F + C + T = 100-------------eq1
15F + C + 0.25T = 100-------------eq2
eq1=eq2 .solve to get F=3T/56 ;F=3,T=56,C=41


a) There is no need to consider their meeting pt at all.the train has been running for 90miles/(60miles/hr)=1.5hrs.bird flies till train reaches destination frm strting pt.so bird flies for1.5hrs at the vel given(90).so dist=1.5*90=135miles

b) time of train=1hr.so dist of bird=60*1=60miles



(a) u don't need to sum it up.since it's a knock out only 1 person emerges winner finally.so15+1=16is answer.becos after15 matches finally we shud've 15losers and 1winner.

(b) 49:its always one less than no of players as per the idea given above.so no need to check okay cos its always true.ans is 49.


Let x= current age
4(x+4)+5(x+5)=10x ;so x=R 41 years


37(x-y)=x^2-y^2. u no tht x^2-y^2=(x-y)(x+y).so (x-y) cancels on both sides to give x+y=37.so sum of unequal halves=37 which is the req answer.


R ans:7 teams okay.for a match u need 2 teams.suppose there r totally 'n 'teams.
Now uve to choose 2 teams out of 'n' teams.so answer =no of such choices=no. of possible combinations. So we've ans = nC2(ncombination2)=21;solve to get n=7.
Sol: n(n-1)/2=21. so n=7.if u don't understand c the graph below
each team plays no. of matches=no of teams ahead of it. One bar '|' represents one team.
| | | | | | | ------------7
6 5 4 3 2 1 0 -----------21
last team is written as 0 matches becos this team has already played with all other teams-hence sum of matches =6+5+4+3+2+1=21 which is correct only if no of teams =7


R 14
1. G+2=j-2
2. 2(G-2)=J+2.
solve these 2 to get
J=14


a). Sol:each mky takes 8 min to eat a banana

b).ans:8m=48 m=6


Use sets and venn diagram to solve such questions.a,b ,aub,anb etc.
12=tennis+leave
18=jog +leave
so jog-tennis=6
again jog+tennis=14.so solve and get jog=10,leave=8,tennis=4.so tot=22


Ans= 32*2 + 30*2=124
