Answer:

The answer is "Option b".

Explanation:

In the given-code variable "userEntry" is defined that prompt the user to input value and in the next step, the conditional statement is used, which checks the input value is not a number and greater than 500 with use of OR operator. if the condition is true it uses the alert box to print the message, that's why in this question except "choice b" all were wrong.

Given positive integer numinsects, write a while loop that prints that number doubled without reaching 100. follow each number w
ELEN [110]
Please provide the language you're using when you ask for programming help, otherwise you aren't going to get the answer that you are looking for.

Here it is in Java, and I'm assuming the number is given via user input? Otherwise, just remove the user input function and replace the integer with a value of your choice. Note, that this isn't the full code; only what is relevant to the question.


public static void main(String[] args) {
    int num = numInput(10);
    printDoubles(num, 100);  // You can create a user input function for
                                             // maxValue if you wanted to.
}

/**
 * Receives user input between 0 and the absolute value of maxInput.
 * @param maxInput The largest absolute value that can be input.
 */
private static int numInput(int maxInput) {
    Scanner sc = new Scanner(System.in);

    maxInput = Math.abs(maxInput);

    int num = 0;
    while (!(num > 0 && num <= maxInput)) {
        num = sc.nextInt();

        if (!(num > 0 && num <= maxInput)) {
            System.out.println("Input too small or too large");
        }
    }

    return num;
}

/**
 * Continues to print out num doubled until maxValue is reached.
 * @param num The number to be printed.
 * @param maxValue The maximum value (not including in which num can                                       be doubled to.
 */
private static void printDoubles(int num, int maxValue) {
    if (num >= maxValue) {
        System.out.println("No output.");
    }

    while (true) {
        if (num >= maxValue) {
            break;
        }

        if (num < maxValue) {
            System.out.print(num + " ");
        }

            num *= 2;
    }

    System.out.println();
}
