the 3rd,7th,11th,15 in array C.
the 4th 8th, 12th 16th in array D

Why do you need separate arrays? Just use the index array and a simple expression for figuring out the index.

Using a basic for or while loop, perhaps:

set i and j to zero
while(i is less than 12) {
  a[j]= index[i++]; 
  b[j] = index[i++];
  ... etc.
  j++;
}
