there are 20 questions all in techinical paper and 36 questions in appititude te
st
in appititude thay have given all diagrams and asked to find what comes next
thay are quite easy and i hope if u practice r.s aggraval u can do it easily
for tecnical thay have given 1 hr for 20 questions and for not technical thay ha
ve given only 40 min
and 36 questions
this is the paper i have right now
1. main()
{
fork();
fork();
fork();
printf("\n hello");
}
How many times print command is executed?
2.main()
{
int i,*j;
i=5;
j=&i;
printf("\ni= %d",i);
f(j);
printf("\n i= %d",i);
}
void f(int*j)
{
int k=10;
j= &k;
}
output is
a 5 10
b 10 5
c 5 5
d none
3.
some question on pipeline like you have to findout the total time
by which execution is completed for a pipeline of 5 stages.
4.
main()
{
int *s = "\0";
if(strcmp(s,NULL)== 0)
printf("\n s is null")p
else
printf("\n s is not null");
}
5.
some syntax which returns a pointer to function
6. size of integer is
a. 2 bytes
b 4 bytes
c. machine dependant
d compiler dependent.
7.max and avg. height of sorted binary tree
a. logn n
b n logn
8.
some question. like the number was shifted everytime by one and bitwise and with 10000000.
one was supposed to find what the code was doing.
I feel the answer was most probably finding decimal value.
9. int a[5][4]
int is 2 bytes base address for array is 4000(Hexa)
what will be addr for a[3][4]?
int is 4 bytes same question.
10.
implementation of priority queue

Series.
1. Interchange of letters in a word and the adjacent letters are also to be changed. given letters series like [also few condotions]
AAABBB=
ABABAB=
LET QUESTION IS ABBAAB
If we apply 25 on this it means we have to interchange the letters at positions 2 and 5, and we have to change the adjacent letters 2 and 5 from A to B and B to A.
That is q's A B B A A B
after Step 1 i.e interchange 2 and 5.
now change adjacent elements of 2 and 5...finally answer becomes
Ans: B A A B B A
//Hint: As per question papers 5 questions above like but numbers
change.

a) 25 b) 34 c)25 & 34 d) noneSECTION II
1. Given the function f(n a b c ) = ac if n=1
f(n a b c) = f( n1 a b c) + f( 1 a b c) + f( n1 b a c )
if n > 1
f( 2) = ?
Ans: f( 2 a c b ) = ab + ac + bc.
2. similar question in functions.
3. [ based on function in 1.] f( 4 a b c ) the number of terms is...?
Ans: f( 4 a b c ) = f( 3 a c b ) + f( 1 a b c ) + f( 3 b a c ) etc.
= 5ab + 5ac + 5bc.
4. f( 5 a b c ) = ?

F(X)= 2X1 + f(X1) if X NOT EQUAL TO ZERO
if f(X=0)=0
9. f(5) VALUE
a)15 b)24 c)22 d)NONE
10.f(f(2))
11.f(16) f(15)
12.f(16)+f(15)480
13.f(f(x))=81 THEN VALUE OF X=
14.f(X)=4f(X1) THEN VALUE OF X=
15.f(X)= f(X1)+f(X2) FOR X>1 THEN X=
16.f(X)f(X1)=f(X8) FOR X>5 THEN X=
SECTION III:
###In the follwing questins we r giving 'aword' which may not have any
meaning.Find differnet possible words or palandrams for the word as per que.
I. for the following find no of distinct words that can be formed.

The Naughty `C'
For Novice and Intermediate C Programmers
To get the answer highlight the answer line ( It may not be there )
Find MAXIMUM of three distinct integers using a single C statement
Ans : d= (a>b) ? ((a>c) ? a : c)) : ((b>c) ? b : c ))
Swap two variables without using any extra variable
Ans : a=a+b;b=ab;a=ab;
Construct a doubly linked list using a single pointer in each node
Ans :
int i=0; while(i=0) printf("%d",++i); Guess the output
Ans : The Loop is not executed, since the assignment statement returns the assigned value zero which is equivalent to false in C
int i=0; while(i=1) printf("%d",++i); Guess the output
Ans : The Loop is executed forever always printing 2, since the assignment statement returns the assigned value one which is equivalent to true in C
int x=2, y=6, z=6; x=y==z; printf("%d",x); Guess the output
Ans : The == has higher precedance than
