Question

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:

Answer 1

Answer:

Following are the Program in Java Language

import java.util.*; // import package

public class Main // Main class

{

 public static void main (String[]args) // main method

 {

int userNum; // variable decleration

Scanner sc2=new Scanner(System.in); // creating the instance of scanner class

System.out.print(" Enter the number:");

userNum=sc2.nextInt(); // Read the number by user

while(userNum/4 >= 2) // iterating the while loop

{

userNum = userNum/4;

System.out.print(userNum);// display number

System.out.print(" ");

}

}

}

Output:

Enter the number:160

40 10 2

Explanation:

Following are the description of the Program

• Read the number in "userNum" of int type by using the instance of scanner class.

• Iterating the while loop divided by the until the reaching value of  less then 2

• In that while loop print the value of userNum.

Answer 2

Answer:

while(userNum > 1){

        userNum = userNum /2;

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

     }
