{
static int a[2][2] = {1, 2, 3, 4};
int i, j;
static int *p[] = {(int*)a, (int*)a+1, (int*)a+2};
for(i=0; i<2; i++)
{
for(j=0; j<2; j++)
{
printf("%d, %d, %d, %d\n", *(*(p+i)+j), *(*(j+p)+i),
*(*(i+p)+j), *(*(p+j)+i));
}
}
return 0;

step1:p=0;
step2:i=0,j=0
*(*(p+i)+j)=a[0]=1
*(*(j+p)+i)=a[0]=1
*(*(i+p)+j)=a[0]=1
*(*(p+j)+i)=a[0]=1
step2:i=0,j=1
*(*(p+i)+j)=a[1]=2
*(*(j+p)+i)=a[1]=2
*(*(i+p)+j)=a[1]=2
*(*(p+j)+i)=a[1]=2
step3:i=1,j=0
*(*(p+i)+j)=a[1]=2
*(*(j+p)+i)=a[1]=2
*(*(i+p)+j)=a[1]=2
*(*(p+j)+i)=a[1]=2
step4:i=1,j=1
*(*(p+i)+j)=a[2]=3

p[3]={a,a+1,a+2}
first (*(p+0)+0)=a[0]=1 etc
second *(*(p+0)+1)=a[1]=2 etc
third *(*(p+1)+0)=a[1]=2 etc
and last *(*(p+1)+1)=a[2]=3 etc
first (*(p+0)+0)=a[0]=1 etc
second *(*(p+0)+1)=a[1]=2 etc
third *(*(p+1)+0)=a[1]=2 etc
and last *(*(p+1)+1)=a[2]=3 etc
