Question

unit 1 lesson 5 activity 2 edhesive
Write a program which takes a three digit number as an input, then prints the digits of this number one per line in reverse order.

Hint: Break this challenge down into repetitions of the steps used for activity 1. Using multiple variables will let you store digits and intermediate results you need.

Sample run:

Please enter a three digit number:
678

Here are the digits:
8
7
6

Answer 1

Answer:

int n;

cin>>n;

while(n!=0)

{r=n%10;

cout<<r<<endl;

n=n/10;

}

Answer 2

Answer:

import java.util.Scanner;

class U1_L5_Activity_One

{

   public static void main(String[] args)

   {

     Scanner scan = new Scanner(System.in);

     System.out.println("Please enter a three digit number: ");

     int x = scan.nextInt();

     

     int z = (x % 10) % 10;

     int y = (x / 10) % 10;

     x = x / 100;

     

     

     System.out.println("Here are the digits:");

     System.out.println(x);

     System.out.println(y);

     System.out.println(z);

Explanation:

I don't know if this makes sense or not but it works :) To be honest, I'm not sure how I did it so I don't know how to explain it. I hope this helps though! (oh, p.s. my assignment wanted it to be 6 7 8 not 8 7 6 so you might want to fix that!)
