【王道JAVA】【程序 24 根据输入求输出】

题目：给一个不多于 5 位的正整数，要求：一、求它是几位数，二、逆序打印出各位数字。

import java.util.Scanner;

public class WangDao {
	public static void main(String[] args){
		Scanner scan = new Scanner(System.in);
		System.out.print("Input your number: ");
		int n = scan.nextInt();
		int count = 0;
		
		System.out.print("Reverse Print:  ");
		while (n != 0) {
			System.out.print((n % 10) + "  ");
			count++;
			n /= 10;
		}
		System.out.println();
		System.out.println("The figure is:  " + count);
	}
}
