Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space.
Ksenya-84 [330]

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.

<em>import java.util.Scanner;</em>

<em>public class TestClock {</em>

<em>    public static void main(String[] args) {</em>

<em>    Scanner in = new Scanner (System.in);</em>

<em>        System.out.println("Enter the number");</em>

<em>    int userNum = in.nextInt();</em>

<em>    while(userNum>=1){</em>

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

<em>        userNum--;</em>

<em>         }</em>

<em>    }</em>

<em>}</em>

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)
