Half - Adder Implementation using Prolog

-- Leave a Comment
Prolog is a logic programming language associated with artificial intelligence and computational linguistics.

It's my First day of Prolog and here is the Half Added login in Prolog. It is not a solution but it just works.

high(1).
low(0).

xor(X,Y,Sum) :- (((low(X) , low(Y)) ; (high(X) , high(Y))) , low(Sum)) ; (((low(X) , high(Y)) ; (high(X) , low(Y))) ,high(Sum)).

and(X,Y,Carry) :- (high(X), high(Y), high(Carry)) ; (((low(X) , low(Y)) ; (low(X) , high(Y)) ; (high(X) , low(Y))) , low(Carry)).

half_adder(X,Y,Sum,Carry):- xor(X,Y,Sum) , and(X,Y,Carry).

for Xor -> if [(X and Y is low or X and Y is high) and sum is low. ] OR [ (if X is low and Y is high or X is high and Y is low) and Sum is high]

for and -> if (X is high and Y is High And Carry is high) OR [(if X is low and Y is low or X is low and Y is high or X is high and Y is low)  and Carry is low]

low = 0 and high = 1

Output:
prolog task3.pl

The half adder adds two binary digits called as augend and addend and produces two outputs as sum and carry; XOR is applied to both inputs to produce sum and AND gate is applied to both inputs to produce carry. The full adder adds 3 one bit numbers, where two can be referred to as operands and one can be referred to as bit carried in. And produces 2-bit output, and these can be referred to as output carry and sum.
