Do you want to write generic code or do you simply want to use a

loop construct on the actual code you've posted?

Using a loop construct on your actual code will make it worse imho.

with generic code, like:

C(n-1)<= A(n) and B(n-1)

C(n-2)<= A(n)and A(n-1)and B(n-2)

......

C(0)<= A(n)and A(n-1)......and A(1)B(0).

upstair is a example for n=4
