**PAPER:**

**HCL Placement Paper1 (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

/ \
