4 = 0100 now shift to right 1 time. It will become 0010 = 2.
8 = 1000 now shift to right 1 time. It will become 0100 = 4.
Rest is garbage, so the answer is C.

@Gowda.
Arrange your number in three arrays see there is no number for 3rd row, 3rd column. So it's partially initialized which has default value zero.

Why we should consider the rest value as garbage I can take it directly as 2 4 why should go for garbage value. Could you please explain me?

@Chinnu- Rest is garbage means, the other %d's in the printf fuction will print any arbitrary value.. thats known as garbage value..

void main()
{
int x[2][2][2]={1,2,3,4,5,6,7,8}
int *p;
p=&x[2][2][2];
printf("%d",*p);
}
ans is 0 (zero) why

Post or pre increments gives the same result when they are free,like i++ and ++i(i.e.without assignment)

Please make the condition as for(i=1;i<=3;i++) , pre/post increment has no significance here.

But in the right shift. Spaces are filled with 1. Then how 0010 can occur?
