Sasken Placement-Paper

Hi! Friends,

i have attended for SASKEN 1+ walk-in recruitment drive at Corporate office,Domlur ring road, Bangalore on 13th December

 

Their requirement was for RTOS-Nuclius, Linux and Symbian. They have given test(C or C++ your choice) timing for different people(nerly 100 people each batch-total 3 batches were there.

 

I have chosen ‘C’ test paper (set1 & set2), which consists 25 questions,45 minutes:

 

 

 

 1.                   void main()

{

200;

printf(“Typical Problem”);

return 0;

}

Output : “Typical Problem”.// NO warnings & NO Error.

 

 

  1. void main()

{

int a=-60,b=-34;

unsigned int c=-24;

printf(“%d”,c);

return 0;

}

Ans : WARNING: initialized to negative value ‘-24’ to ‘unsigned int’.

 

 

  1. void main()

{

printf(“%u”,-1<<4); \

return 0;

}

Ans : ffff0

 

 

  1. void main()

{

printf(“madhu “);

main();

return 0;

}

ANS : INFINITE LOOP

 

5.   void main()

{

int count=10,*temp,sum=0;

temp=&count;

*temp=20;

temp=∑

*temp=count;

printf(“%d %d %d\n”,count,*temp,sum);

return 0;

}

ANS : 20 20 20

 

 

  1.  void main()

{

char ch;

for(ch=0;ch<=127;ch++)

printf(“%c %d”,ch,ch);

return 0;

}

 

 

  1. void main()

{

int a[3][4]={1,2,3,4,5,6,7,8,9,12,12,14};

printf(“%d %u %u\n”,sizeof(a),a+1,&a+1);

return 0;

}

 

  1. void main()

{

int a[3][4]={1,2,3,4,5,6,7,8,9,12,12,14};

printf(“%d %u %u\n”,sizeof(a),a+1,&a+1);

return 0;

}

If the address location of ‘a’ is 65000 the output=?

Ans : 65000 65016 65048

 

9.  What is the size of a String Variable ?  

10. Good way of representing the variables in RECURSION is ?

a)Static        b)Global         c)Local         d)Register

11.   True/False based on Storage Classes in ‘C’ .

 

12.                    How to call the function for the below : void f1(int **x)

Options:               a) int *x,f1(&x);

b) int x,f1(&x);

c) int *x,f1(&&x);

d) int *x,f1(x);

13.      They asked to choose a program which leads to Stack Overflow, among given 2 Factorial programs(one contains recursive function, & other general loop logic)

 

14. variables of Function calls allocated in :

 

 

a) Stack & Heap,           b) Stack & Data,      c) Data & Register            d) None

15.   #include

Void main()

{

int a=10,j; j=fun(a);

switch(j)

{

case 30 : printf(“Printed 30 \n”);

break;

case 50 : printf(” Printed 50\n”);

break;

default : printf(“Not 30 or 50 “);

break;

}

return 0;

}

int fun(int a)

{

return(a++);

}

16.   malloc() internally calls:            a) salloc()       b) stbrk()        c) alloc()          d) none.

 

17.        #include

 

void main()

{

char *p=”madhu”;

printf(“%c”,p);

return 0;

}

18.     Question based on Structures (some what complicated)    

Some more Questions on Pointers in ‘c’. Three more question based on Unix.
