1ST ANS - DELIVERED ON
2ND ANS BARREN
SO ON
BE PREPARED WITH HIGH FREQUENCY WORDS FROM BARRONS
ALL THE QUESTIONS WERE FROM THOSE 300 WORDS
TECHNICAL " C"
FIRST 5 QUESTIONS WERE VERY TOUGH
REMAINING WERE OK
ANYHOW JUST TRY TO ANSWER MORE QUESTIONS.DONT STICK TO ANY QUES. MOVE ON TO
THE NEXT IN SUCH SITUATIONS.
C Questions
1.a=5,b=3,c=a,b
d=(a,b)
printf(c,d)
ans:c=5,d=3
2.e(int n)
{
if(n>0)
{
...(not clear)
printf("%d",n);
e(--n);
}
return
}
ans:0,1,2,0
3.which has no problem with pointers
int *f1()
{
int n;
return (n)
}
int *f2()
{
int *p;
*p=3;
return p;
}
int *f3()
{
int *p;
p=malloc();
return p;
}
ans:no error
4.header file ->contains declarations.
5.sizeof operator is executed during compile time..
6.*p+=1
*p++
are these two same?
not same.
7.func(int i)
{
static int count;
count=count+i;
}
ans:1+2+3...(counts values does not go after funtion call
8.is('a'<'b') true
10.short int=16 bits
11.4 stmt. ans.int float i;
12.int num[3];
num[3]=2;
ans:first stmt deals with size
second deals with element
13.j=4
for(int i=0;i<5;i++)
{
j++;
++j;
}
output of j.
ans:14
9.char s1[20]="hello world";
s1[5]="\0";
printf("%d",strlen(s1));
printf("%%.%...(not clear)",s1);
}
ans:bad format specifier
14.brace { used in c for what ans:convention
15.parameters in c passed by ans:value.
16.when an array is passed it is by ans:pointer.
17.scanf can read ans:any data type
18.which cant be passed to subroutine.ans:preprocessor directive.
19.to get string of words..ans:gets()
20.external variables can be accesed ans:in functions which use them.

The test cnsisted of 3 sections:
1. Aptitude -> 60 questions(1 hr)
2. Maths -> 15 questions(30 min)
3. C or Java(there is an option) -> 30 questions(1 hr)
1. Aptitude:
Started with fill in the blanks, followed by analogies, antonyms. Next
came the data sufficiency & logical reasoning questions. Then there were
some basic quatitative questions. Finally the aptitude test ended with some
data interpretation questions.
Antonyms of:
Increduluous
Zest
Officious
Analogies:
RANK:INSIGNIA -> PEOPLE:STATUS
FATIGUE:RESTING -> OVERWEIGHT:DIETING
2.Maths:
This part was easy but somewhat tricky.
2.1 A figure with 8 poles was given. Each pole was separated by a distance
of 8m. It was given that a man runs to each pole and back. Asked to find the
total distance to reach the last pole? (Ans: 288)
2.2 Are there more Sundays in a millenium or inches in a kilometre. (Ans:
inches)
2.3 A gambler has the "easy go easy way" policy. He doubles his money the
first time and gives away $1. He trebles his money the next time and gives
away $2. Finally he is left with 4 times the amount he started with. How
much money he had when he started?(Ans: $2.5 check)
2.4 Are there more centimetres in a kilometre or seconds in a day? ( Ans:
centimetres)
2.5 A person purchases goods at three(3) shops successively. Each time he
spends 2/3 of the amount he has. If he is left with 50 paise after the last
purchase, how much money he had in the beginning?
(Ans: Rs 13.5/-)
2.6 & 2.7 Two questions on age. (very easy).
2.8 My double exceeds my half by 2. What am i? (Ans 4/3)
2.9 N packets are transmitted through a network. The probability of a packet
being error prone is P. What is the probability that all packets are
transmitted error free? (Ans (1-P)^N check)
2.10 Y-X^2=25 is a function. What is the y intercept? (Ans 25)
2.11 A machine has N parts. The probabilty that any part fails is P. The
machine fails of any of the part fails. Fine the probabilty that none of the
part fails?(Ans 1-P^N).
2.12 Mexico is 13 hours behind Singapore in time. Singapore itself is 7
hours ahead of London in time. If it is 10 minutes past 4 on Tuesday morning
in London what is the time and day in Mexico?
2.13 If a hen and a half lays an egg and a half, how much will half a dozen
hens lay in half a dozen days?
2.14 A person deals playing cards among people. On the first chance he deals
among 4 people and 3 cards are left. Next he deals amongs 2 and 3 cards are
left. (Don't remember this one exactly..)
2.15
3. C test:
3.1 A question on strings and pointers.
3.2 Which function in C allocates memory and initializes it to zero?
3.3 The compiler equates x[i][j][k] to:
*(*(*(x+i)+j)+k) : no such option was given, i think this is the correct
answer.
3.4 During which phase are _STDC_ and _FILE_ defined.
Options: compiling,preprocessing,coding, assembling,linking.
3.5 What is the function clock() in C used for?
3.5 A question on macros
Options: A macro can contain parameters, macro definition can contain
expressions, macros are processed during the preprocessor stage, macros are
processed at run-time.
3.6 What is the value of 64>>3?
3.7 Value of 0xE & ~0x9?
3.8 Value of 0xB & 0x5?
3.9 How do you redirect the output to a particular file?
3.10 Is there any inbuilt sorting function in C for sorting character
arrays?
3.11 fp=fopen(file.c,"r");
What is the correct declaration for fp?( ans: FILE *fp)
3.12 What will be the output:
int x=0;
for(;;x++){
if(x==4) break;
continue;
}
printf("%d\n",x);
3.13 What is the output:
int i=100;
do
{--i;}while(i>50);
printf("%d\n",i);
3.14 & 3.15 A question on calloc()(which one would give a runtime error) and
another one on pointers
although the code looks correct whats the problem with the logic).
3.16 A qustion on converting a string defined using a character pointer to
lower-case
char s[100]; (Don't remember the question
char *ptr;
ptr=s;
*ptr="Hello World"
3.17 Assume 2's complement arithmetic
int m=-14;
int n=6;
int o=m%++n;
n+=m++%o
printf("%d%d%d",m,n,o);
3.18 The type returned by sizeof is:
Options: size_t,int,unsigned int
3.19 int a=1000,b=1000; Which is the shortest statement for preventing the
integer overflow exception
Options: long c=long(a)*long(b), long c=a*b, long c=long(a*b),c=(long)a*b
3.20 A short int=16 bits. What is the maximum value which can be displayed
using it.
3.21 struct typedef cust_record{
char name;
}CUSTOMER_REC;
CUSTOMER_REC customer[50];
How will you access the structure variable name.
(ans:customer[i]->name check)
