1.  What would be the equivalent pointer expression for referring the array element a[i][j][k][l]
A. ((((a+i)+j)+k)+l)
B. *(*(*(*(a+i)+j)+k)+l)
C. (((a+i)+j)+k+l)
D. ((a+i)+j+k+l)

Answer: Option B

Explanation:

If we want to refer one dimensional we just use single pointer ie like *p, if we need to refer two dimensional we have to use double pointer reference ie *(*p),,if we have to refer 4 at a time just use 4 pointer statement i.e. *(*(*(*(p))))and so on.....

ptr[0]------>*(ptr+0);
ptr[1]------>*(ptr+1);

Like that:

a[i]---->*(a+i);
a[i][j]---->*(*(a+i)+j);
a[i][j][k]---->*(*(*(a+i)+j)+k);
