    question about writing a java script

    hey guys "

    I have question about writing a java script code equivalent to the following figure :




    I've written the code like this ,


    <html>
    <body>

    <script type="text/javascript">
    var x;

    x = 12;

    while (x != 0)
    {
    document.write(" x = " + x +"<BR>");
    x = x - 3;

    }
    document.write("DONE");

    </script>

    </body>
    </html>


    is my answer right or wrong ?? <

    Looks fine to me.

    Now what about if the first instruction was "set number to 13".

    What is then wrong with the flow chart? What is then wrong with the code?

    Oh...one VERY minor point.

    You *CAN* write
    Code:
         x = x - 3;
    as
    Code:
         x =- 3;
    Don't change your code. Just FYI.

    Hmmm....*technically* you are doing too much.

    The instruction says "write out the value of the number...".

    You are writing "x =" in addition to that. <grin/>

    The computer is always right. The computer is always right. The computer is always right. Take it from someone who has programmed for over ten years: not once has the computational mechanism of the machine malfunctioned.

    (Actually, it's just that my fingers get ahead of my vision/brain at times. I so often type "hte" and "thsi" that it's scary. And as I was typing this I tried to put in "tyep"...sigh.)
