The second form is wrong. A two dimensional pointer does not equal to a two dimensional array. But you can use an one dimensional pointer to reference the two dimensional array.int arr[1][20];int *pTwoDem=(int*)arr;Now you can use *(pTwoDem+10) to replace arr[0][10].

C++
int arr[1][20];
int *pTwoDem=(int*)arr;

Now you can use *(pTwoDem+10) to replace arr[0][10].
