Question
Half adders have no scope of adding the carry bit resulting from the addition of previous bits.
Solution
That's correct. A half adder is a type of digital circuit that performs the addition of two binary numbers. It has two inputs, for the two bits being added, and two outputs, for the sum and carry. However, it does not have an input for a carry from a previous bit, so it cannot add this in. This is why it is called a "half" adder - it does only half the job of full addition. If you need to add binary numbers that are more than one bit long, you would need to use a full adder, which does have an input for a carry from a previous bit.
