Placement Papers - HCL

Hi Friends

I don\'t remember the questions of the HCL paper. But i can give u the idea about the paper.
There are total of two sections (Time: 1 Hour 20 min)
section 1 contains 45 questions (C,C++,8086 microprocessor(5 ques),networking(5 ques))
section 2 contains 20 questions (aptitude, reasoning)

section 1
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.
some question i remember are
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 folowing 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?

Section II:
1) 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?
2) 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 mary 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..
3) 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?
