wait i update clear picture .

check

I am not inderstanding few points:

1. Why address of a[0] and a[1][0] is same?

2. As a[0] is pointing to first 2darray , what a[1][0] pointing to?

3. why we divided by 4 in a[1]-a[0]?

---

1.a[1] and a[1][0]  address same but meaning is different

   a[1] talk about 2d array of size [3][2]

   a[1][0] talk about 1d array [2]

2. As a[0] is pointing to first 2darray , but  a[0][0] pointing to first 1 d array

3. why we divided by 4 in a[1]-a[0] beacuse we skip row which is define [3]  each contain 2 elements so size 2*2= 4.

@Anirudh, a[0] points to a 2-D array of [3][2], so scaling factor is sizeof 1-D array in first part.,i.e., $4$ and a[1][0] points to 1-D array $2$ element. so, scaling factor $=$ sizeof an element in $1-D$ array i.e., $2$B

Yes ..
