Dated : 1st of August,2011.
There were two rounds - 1)a 30 min Technical paper based on C and C++ with 16 ques
2)a 60 min Aptitude paper with 2 sections(Logical Reasoning and Quantitative aptitude) with 50 ques.
1st round(Technical paper) :
1. If integer needs two bytes of storage, then maximum value of an unsigned integer is
a. 2^16-1
b. 2^15-1
c. 2^16
d. 2^15
2. If integer needs two bytes of storage, then maximum value of a signed integer is
a. 2^16-1
b. 2^15-1
c. 2^16
d. 2^15
3. What is the output of
printf (“%d”, printf(“tim”) );
a. results in a syntax error
b. outputs tim3
c. outputs garbage
d. prints tim and terminates abruptly
4. Length of string “correct” is
a.7
b.8
c.6
d. implementation dependant
5. Consider the following program fragment
char c= ‘a’;
while(c++ <= ‘z’)
putchar(xxx);
If the required output is abcd…wxyz, then xxx should be
a. c
b. c++
c. c-1
d. --c
6. Consider the function
find(int x, int y)
{
return ((x< y ?0:x )?>;
}
The call find (a, find (a, b) ) can be used to find
a. maximum of a, b
b. positive difference of a, b
c. sum of a, b
d. minimum of a, b
7. If abc is the input, then the following program fragment
char x, y, z;
printf(“%d”,scanf(“%c%c%c”, &x, &y, &z));
results in
a. a syntax error
b. a fatal error
c. segmentation violation
d. printing of 3
8. Consider the statements
putchar(getchar());
putchar(getchar());
If ab is the input, the output will be
a.an error message
b. this can’t be input
c. ab
d. a b
9. The operators ., ||, <, = if arranged in the ascending order of
a. . , || , < , =
b. =, < , || , .
c. =, || , <, .
d. <, || , = , .
10. In the following program fragment
unsigned i=-1;
int j = -4 printf(“%u”, i+j);
prints
a. garbage
b. -3
c. an integer that changes from machine to machine
d. none of the above
11. The following program fragment
for( i=3; i<15;i+=3);
printf(“%d”,i);
results in
a. a syntax error
b. an execution error
c. printing of 12
d. printing of 15
12. The following description of the program, please pick the wrong one?
int main(void)
{
int i= 100;
int*pi=&i;
int**dpi = π
}
a. dpi to store a pointer with the address for pi is a double pointer
b. (*pi==i) is true.
c. (*pi== **dpi)is true.
d. (*dpi == 100) is true
13. Below, please find the results for the program do?
int counter = 0, i;
for(i=0;;i++)
{
if (i < 100) continue;
counter ++;
if (counter == 100) break;
}
printf(%d%d”,i, counter);
a.199 100
b. 200 100
c. 199 99
d. 200 0
14. See below for a description of the defined array, please choose the
wrong thing ?
int a [] = {10,20,30,40};
a. successive one-dimensional array of elements in the array a[1], a[2] is located in the contiguous memory space.
b. a[1] and a* (a+1) is the same.
c. During the initialization of an array; array size must be specified
otherwise the initial value at compile error occurs
d. & a[1] which has a +1 value, such as the address
