halfAdder : it accepts 2 bits as input arguments. It adds these bits and returns 2 bits as output arguments: the sum and the output carry

What is this for? How are the bits passed in? I.e., what are the variable classes involved?

If the input bits are numeric scalars or logical values, b1 and b2, then the sum bit, 's', would be:

s = b1 xor b2;

or else

s = (b1&~b2) | (~b1&b2);

These are equivalent. That leaves you with the 'carry' bit to figure out.
