    Temp Conversion Program...Help please

    Hello everybody on this group. I have this program that is supposed to
    display a temp. conversion from fahrenheit to celsius, can anybody
    kindly can tell me what is wrong? Thanks.

    var fahrenheit = new Array();
    var celcius = 0;
    for (var i = 0; i <= 100; ++i) {
    fahrenheit[i] = i;
    }
    for (var j=0, j<100, ++j) {
    celcius = (fahrenheit[i] - 32) * .55
    document.write( fahrenheit[i] + " degrees Fahrenheit is equal to "
    + celcius + celsius.<br />);
    }
    // STOP HIDING FROM INCOMPATIBLE BROWSERS -->
    </script>

      for (var i = 0; i <= 100; ++i) {

      for (var j=0, j<100, ++j) {

      notice the <= in the first line and the < in the second.

      notice also that u dont need the array.

      and also that you are using document.write in the head section, and not
      in the body section.

          Forget using HTML comments inside script elements, particularly if your
          browser is interpreting this as genuine XHTML - in which case
          document.write may cause you some heartache too.

          But never mind...

          This array is not required.
          [color=blue]
          > var celcius = 0;[/color]

          This variable is not needed. If the intention is to write conversions
          for 0 to 100 degrees Celsius to Fahrenheit, then the following:

          for (var i=0; i <= 100; ++i) {
          document.write( i + ' degrees Celcius is equal to '
          + (Math.round(i*9/5 + 32))
          + ' degrees Fahrenheit.<br />'
          );
          }

          should do the trick, unless the point of the exercise was to use an array?

          [...]

              Hi nyy, this is King Sapingo, remember me ;-)

              I have a few comments:

              why XHTML

              as someone else mentioned in another post,
              there are no /incompatible browsers/
              (in other words, you don't need this,
              unless you actually publish it as XML (XHTML)
              then you need the <![CDATA[ definition)

              anyway, back to your problem:

              ^ ^
              for (init ; while;incr)
              you also probably mean j<=100
              since you said i<=100 earlier

              for (var j=0; j<=100; ++j)
              [color=blue]
              > celcius = (fahrenheit[i] - 32) * .55[/color]
              ^ ^
              didn't you want j instead of i? and end the line with ";"
              (you will be surprised about some of the results "* 0.55" yelds ;-)

              the same j instead of i?

              you probably want this in "quotes"[color=blue]

                  Your ".55" should be written "0.55". Javascript will understand either,
                  bur relying on a half-bare decimal dot is liable to lead to human error.
                  See, if you have access, IUPAP-25 / SUNAMCO 87-1.

                  The conversion factor is in fact not 0.55 but bigger.
