{
   print(”0 %f, 1 %f, 2 %f “,arr[0][0],arr[0][1],arr[0][2]);
}
main()
{
  int a[ ][ ]={ {1,2,3}, {4,5,6} }
  int ** arr=a;
  print(arr);
  arr++;
  print(arr);

(a)  No Error
(b)  Free can’t be used for p
(c)  Compiler Error
(d)  In printf we should use *p instead of i.


4. What is the output of the following

   i=!i>3;
   printf(”%d”,i);
}

(a) 0
(b) 5

(d) Error


5. What is the output of the following
