As you know pointers & arrays both move consecutive

how come it be totally different

Smith# wrote:

Because the next pointer in the **ptr can be made to point to some other *p pointing somewhere. But here that's not the case.. it's array,

int a[2] = { 0,1 };
int* pa = a;

*pa = 5;

pa[1] = 6;

int a[2][2] = { 1,2,3,4 };
a[1,1] = 5;

int **ppa = a;
ppa[1][1] = 8;
