TASK 1 You need to employ a full-adder to perform addition and subtraction operations. may check your full-adder according to the truth table (see document) The full-adder can be implemented by the following formulas (see document), You You are encouraged to implement the full-adder using basic logic gates. A 1-bit alf-adder is implemented at first, which contains two logic gates: a XOR gate and an AND gate. And then, a 1-bit full-adder is built using two half-adders nd an OR gate. when u call the function halfadder, you need to pass the address of the alue to the output parameter. use & to get the address of the value. If u want to set a output value, use to access the memory and set it. / write your code here
