C while loops into assembly ??

Consider the C code function below:

void qwerty(int *x, int *y, int size)
{
  int k=0;
  while ( k < size ) {
     *(x + k) = *(y + k);
     k++;
   }
}

ii) Construct an ARM assembly code version which implements the C code within the function qwerty. You may assume that registers a1 and a2 contain the pointers x and y respectively, and that register a3 contains the size argument.

Have fun failing at CS, when you can't even answer the most basic tasks.
