Question

Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space.

Answer 1

Answer:

   while(userNum>=1){

       System.out.print(userNum/2+" ");

       userNum--;

        }

Explanation:

This is implemented in Java programming language. Below is a complete code which prompts a user for the number, receives and stores this number in the variable userNum.

import java.util.Scanner;

public class TestClock {

   public static void main(String[] args) {

   Scanner in = new Scanner (System.in);

       System.out.println("Enter the number");

   int userNum = in.nextInt();

   while(userNum>=1){

       System.out.print(userNum/2+" ");

       userNum--;

        }

   }

}

The condition for the while statement is userNum>=1 and after each iteration we subtract 1 from the value of   userNum until reaching 1 (Hence userNum>=1)
