Here I am looking for the last year Placement Paper TATA ELXSI, can you please provide me the same???

As you are looking for the last year Placement Paper TATA ELXSI, so here I am sharing the same with you

TATA Elxsi Placement Paper

1. nt a=9;
switch(i)
{
printf("hello");
case 9 : printf("abc");
break;
default : printf("def");
}
what would be the output ?
ans : the program will compile correctly with no errors but will give undesirable results
2. int z[3]={1,2,3};
int *p=&z[1];
int x=*p++;
printf("%d",x);
ans. note here that the value of *p will be assigned to x and then p is incremented therefore x=2
3. #define paste(a,b) a##b
main()
{
int a=3,b=6;
paste(a,b);
return o;
}
question. what code will be replaced at the call of the macro
options : (a,b) a,b (a,b)
(ab) a,b (ab)
(a,b) ab (a,b)
ans. not able to work it out
4. some structure declaration was given
struct abc
{
int a : 4
char c : 2
int abc;
}
ques. what will be memory allocated to it when we define an object of this structure

ans . the bits are added and rounded of 2 next higher byte
eg. 5 bits - 1 byte
1 bit - 1 byte
9 bits - 2byte
5. some ques. on memory allocation so clear ur funda of memory allocation properly
6. To declare a boolean variale in C what method we follow ans. using bit feilds
7. What does painter's algo. is for in graphics ans. don't know
8. Which is more efficient calling a function by its name or by using a pointer to the function
9. External functions and external variables are all global
10. There are 5 jobs A B C D and E u have to schedule these jobs using the SPT , DD and STR ( i cant
remember
11. the fullforms) and job processing time was given constraints:
Spt = DD
STR = DD - SPT
ANS: using this table u can solve the eqs Freshersworld.com
spt E C A B D
DD E A C B D
STR E A/B D C
order of excution
12. c = prt/ropd prt = production/rate ropd = rotations Nt = T/c E = T/Na * c Na = whole number
according this formula there WERE 5 qs
13. A B C D E are 5 boys and find the ages of them given 1) B-A = 5
2) B>A
3) D>F
4) E-D<2
5) D-F > 2
6) All of the above are false
14. About the graphics similar to java function draearc drawrect, find the area, center by giving values to function
drawarc.
1. about process ( os )
2. stacks (data struct..)
3. graphs ( binary trees)
4. time complexity of the c program they had given
5. c program ( recurrsion find the no. of print stat exec. in the recu. func. ans. 4)
15. About the soft. engineering i.e identify the phases
1) collecting the information - requirement analysis phase testing or design .. ( similarly identify the 5 statemnets
they had given)
16. Choose the correct expression
((())) correct
()(()( incorrect.
