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.
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:
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.
Thank you!
