Question

CHALLENGE ACTIVITY 5.2.3: Basic while loop expression. Write a while loop that prints userNum divided by 4 (integer division) until reaching 2 or less. Follow each number by a space. Example output for userNum = 160: 40 10 2 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 160, then with userNum = 8, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks". Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Programend never reached." The system doesn't print the test case that caused the reported message.

Answer 1

Answer:

input with 160

output: 40 10 2

Explanation:

import java.util.Scanner;

//Define the class divideFour

public class divideFour

{

  public static void main(String[] args)

  {

      //Declaration of variables as integer

      int userNum;

      //set an input

      userNum = 160;

      //Run the while loop until the conditions are not satisfied.

      while(userNum>2)

      {

          //Divide userNum by 4 and store it in the same.

          userNum = userNum/4;

          //Print the new value of the userNum

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

      }

      System.out.print("");

  }

}
