Question

Given positive integer num_insects, write a while loop that prints that number doubled up to, but without exceeding 100. Follow each number with a space. Sample output with input: 8 8 16 32 64

Answer 1

Answer:

import java.util.Scanner;

public class CocaColaVendingTest {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter value for number of insects");

       int num_insects = in.nextInt();

       while (num_insects<=100){

           System.out.print(num_insects);

           num_insects*=2;

           System.out.print(" ");

       }

   }

}

Explanation:

In the code above written in Java.

The user is prompted to enter a positive value for the number of insects

This is stored in a variable num_insects.

Using a while loop with the condition while (num_insects<=100). The num_insects is printed out. Then it is doubled followed with a space.

It continues until the condition in the while loop is no longer true
