1. Write a while loop that lets the user enter a number. The number should be multiplied by 10, and the result assigned to a variable named product. The loop should iterate as long as product is less than 100

import java.util.Scanner;

public class num6 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int product=0;

       do{

           System.out.println("Enter a number");

           int num = in.nextInt();

           product = num*10;

           System.out.println("The product is " + product);

       }while (product<100);

  }

}

Explanation:

In the Java program above, The user will be prompted to enter a number.

The number is multiplied by 10 and assigned to a variable called product.

A dowhile loop has been implemented to check the variable product

As long as this variable is less than 10, the user will be prompted to enter another number.

i think the answer is b.
