int main(){
int a[3][4] = {{1,2,3,4},{9,10,11,12},{13,14,15,16}};
printf("%d\n", a[0][0]);
printf("%d\n", a[2][3]);
printf("%d\n", *(*(a+2)+3));
printf("%d\n", *(*a + 2*4 + 3));
}
Output:
1
16
16
16Note:
for int a[m][n], we can use *(*(a+x) + y) and *(*a + x*m + y) to access a[x][y]. In both methods, we need to dereference twice.
