Create the following circuit components. Your CCT file must contain the following component being tested using switches$/$probs$/$hex keyboard$/$hex display after being saved as a component in your library:

$1.4-$bit binary adder with $,$ X$3$:$0$ Y$3$:$0$ Z $,$ as input, S$3$:$0$ and C as output $($c$2-1.$cct$)$; Requirement: your CCT file must show the component being tested using HEX keyboards and HEX displays

$2.4-$bit binary adder$-$subtractor with XOR and a $4-$bit Adder, the component should use X$3$:$0,$Y$3$:$0$ Sub as input S$3$:$0$ and C as output $($c$2-2.$cct$)$;

Requirement: your CCT file must show the component being tested using HEX keyboards and HEX displays
