1)Is it possible for a full adder to add three e.g 4 bit numbers? I mean I know the full adder has 3 inputs and two outputs but the second bit of C comes from the previous block (as shown in the image below).I mean C1 comes from the frist block and I dont provide it. And this mean I can only choose the first bit of C0. So it does not add 3 integers, right? 2)Is it possible to get the sum of k n-bit integers with full adder circuit? Thanks in advance!
