Question

Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 40: 20 10 5 2 1 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 40, then with userNum = 2, 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 "Program end never reached." The system doesn't print the test case that caused the reported message.

Answer 1

Answer:

public class Main

{

public static void main(String[] args) {

    int userNum = 40;

    while(userNum > 1){

        userNum /= 2;

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

    }

}

}

Explanation:

*The code is in Java.

Initialize the userNum

Create a while loop that iterates while userNum is greater than 1. Inside the loop, divide the userNum by 2 and set it as userNum (same as typing userNum = userNum / 2;). Print the userNum

Basically, this loop will iterate until userNum becomes 1. It will keep dividing the userNum by 2 and print this value.

For the values that are smaller than 1 or even for 1, the program outputs nothing (Since the value is not greater than 1, the loop will not be executed).
