HCL Placement Paper (Technical & Aptitude)

In this section there are mainly questions based on C language like find the errors in the program and what is the output of the following program.

1) int i=10;

printf("%d %d %d",i++,i++,i--);

there is one or two more question on increment operator

2) Two question on redirection operator(>>)

3) int i=10;

if(1,i++,++i)

printf("The value for i is %d",i);

4) one question on structure and u have to fine the error in the syntax

5) int a=10,b=33;

a=a^b;

b=a^b;

a=a^b;

printf("%d %d", a,b);

6) int *a;

int (*b)();

printf("%d %d",sizeof(a),sizeof(b);

7) # define SQR(a) (a*a)

void main()

{

printf("%d", SQR(5));

}

8) And in another question # define directive is declared in the main() function of the program and u have to predict the output of the program.?

9) what is the time complexity of bubble sort (Ans: O(n^2))

10) what is the preorder traversal of the following tree some tree is given (this is not the actual tree given in the paper only idea)

A

/ \

B C

/ \

D E

/ \

F G

11) x=2,y=6,z=6

x=y==z;

printf(%d",x)

12) What is the size of the address bus and data bus in 8086?

13) address of IVT in 8086?

14) some 6 guys are there A,B,C,D,E,F(say) and u have to adjust in the row. and some statements are there like A & D can't be adjacent E, A have one vacant area in between.. like that and there are 5 questions are based on that?

15) this one is tricky .. there are two groups . one is many brothers can mary one sister of other group. and second is many sister can marry one brother of other group and some statements are there like V & U is father of S, X is the only grandmother of S ...like that.. And there are 6 question based on that..

16) and rest of questions are purely aptitude & quant based. like there are two questions on coding if MYSORE is code like MEMEME then how TAMILNADU is coded?
