Question

**Java**
I'm trying to make a program that adds and subtracts binary numbers.
The way I was assigned to do it is take two numbers, then turn their sum and difference into binary code while only showing them in binary.
Like.. The steps that I have?
The user inputs two numbers.
The code prints the two numbers in binary.
Then the sum and difference is calculated of the original numbers, and printed in binary.
What I have so far:
import java.util.Scanner;

public class Kiana{
public static void main (String[]args){
Scanner input = new Scanner(System.in);
Along those lines.

Answer 1

there are different ways of adding binary numbers including 2s complement and 1s complement.

you can look up some code to convert integers to binary, I wrote something here if you're lazy (but it's in cpp and not java) https://gist.github.com/bibsoft/6796795

Answer 2

(1203)_10

1203/2 = 601 + R1
601/2 = 300 + R1
300/2 = 150 + R0
150/2 = 75 + R0
75/2 = 37 + R1
37/2 = 18 + R1
18/2 = 9 + R0
9/2 = 4 + R1
4/2 = 2 + R0
2/2 = 1 + R0
1/2 = 0 + R1

Answer 3

if we dont want to divide, then k mod 2 creates the list as well

Answer 4

once we have placement determined, then its just picking rules for adding the binary vectors, might want to keep a carry box to add in as needed

Answer 5

just a thought ....
