3.CHAR A[10][15] AND INT B[10][15] IS DEFINED WHAT'S THE ADDRESS OF A[3][4] AND B[3][4] IF ADDRESS OD A IS OX1000 AND B IS 0X2000
A. 0X1030 AND 0X20C3
B. OX1031 AND OX20C4
AND SOME OTHERS..

4. int f(int *a)
{
int b=5;
a=&b;
}

main()

{
int j;
for (j=0;j<16;j++)
{
if (i & (0x8000>>j))
printf("1");
else
printf("0");
}
}
what's the purpose of the program

7.#define f(a,b) a+b
#define g(a,b) a*b
main()

m=2*f(3,g(4,5));
printf("\n m is %d",m);
}

what's the value of m
a.70
b.50
c.26
d. 69

8.main()
{
char a[10];
strcpy(a,"\0");
if (a==NULL)
printf("\a is null");
else
printf("\n a is not null");}

what happens with it .
a. compile time error.
b. run-time error.
c. a is null
d. a is not null.

9. char a[5]="hello"
a. in array we can't do the operation .
b. size of a is too large
c. size of a is too small
d. nothing wrong with it .

10. local variables can be store by compiler
a. in register or heap
b. in register or stack
c .in stack or heap .
d. global memory.

11. average and worst time complexity in a sorted binary tree is

12. a tree is given and ask to find its meaning (parse-tree)
(expression tree)
ans. ((a+b)-(c*d)) ( not confirmed)

13. convert 40.xxxx into binary .

14. global variable conflicts due to multiple file occurrence is resolved during
a. compile-time
b. run-time
c. link-time
d. load-time


15.Two program is given of factorial. one with recursion and one without recursion . question was which program won't run for very big no. input because
of stack overfow .
a. i only (ans.)
b. ii only
c. i& ii both .
c. none


16.
struct a
{
int a;
char b;
int c;
}

union b
{
char a;
int b;
int c;
};
which is correct .
a. size of a is always diff. form size of b.(ans.)
b. size of a is always same form size of b.
c. we can't say anything because of not-homogeneous (not in ordered)
d. size of a can be same if
