I'm hoping this is very simple. I am currently using a random quote
generator on our intranet.
I have 17 quotes, when I add in an 18th and change the makeArray
number the code seems not to work.
This works:
<script LANGUAGE="JavaS cript">
function makeArray(len) {
for (var i = 0; i < len; i++) this[i] = null;
this.length = len;
}
quotes = new makeArray(17); //This Number is a variable relating to
the Number of Quotes//
quotes[0] = "\"Imaginat ion is more important than knowledge \" Albert
Einstein";
quotes[1] = "\"One should always play fairly when one has the winning
cards. \" Oscar Wilde"; ...............
.............
quotes[16] = "\"Well, if I called the wrong number, why did you answer
the phone? \" James Thurber";
function rand(n) {
seed = (0x015a4e35 * seed) % 0x7fffffff;
return (seed >> 16) % n;
}
var now = new Date()
var seed = now.getTime() % 0xffffffff
</script>
<script LANGUAGE="JavaS cript">
var quoterand = quotes[rand(quotes.len gth)];
if (quoterand.leng th < 40) {
document.write( quoterand+"")
} else { document.write( quoterand)
}
</script>
All I od is add another quote, increase the makeArray and it goes
wrong. Any ideas?
TIA

Hi Luke,
For what you are trying to do, the code used is complete overkill.
Have a look at this.
<html>
<head>
<script type="text/javascript">
var quotes = ["MyFirst Quote" , "Q2" , "Q3", "Q4", "Q5", "Q6", "Q7", "Q8",
"Q9", "Q10", "Q11", "Q12", "Q13", "Q14", "Q15"];
function getRandomQuote( ){
numberOfQuotes = quotes.length;
randNum = Math.floor(Math .random()*numbe rOfQuotes);
return quotes[randNum];
}
</script>
</head>
<body>
Hai, the random quote is:
<br>
<script type="text/javascript">
document.write( getRandomQuote( ));
</script>
</body>
</html>

[...] function getRandomQuote( ){
numberOfQuotes = quotes.length;

return quotes[randNum];
}
Very concise, but you could take that a little further:
function getRandomQuote( ){
return quotes[Math.floor(Math .random()*quote s.length)];
}

Well Fred, :-)
You are right of course, but I was trying to keep the steps readable for the
Original Poster.
For educative purposes. :-)

Thanks one and all (at Developersdex)
Worked like a charm, and much cleaner code.

I have a simulation program that calls the rand() function at various points
while it executes.
For the user interface that displays statistics etc. while the program runs,
I use the Lazarus GUI library, which is based on GTK. Depending on which
libraries I link in, I can have either a GTK1 or GTK2 user interface.
I'm finding that the simulation behaves differently depending on whether I
link with GTK1 or GTK2.

the .NET one does not generate a wide enough range of values as i have to

Hey guys
Using Random(), how random is it, is it possible to be predicted? I have a
requirement for a very good random number generator. I was doing something
such as:
Random randomSeed = new Random((int)_seedTimer.ElapsedTicks);
_random = new Random(randomSeed.Next(0,99999999));
return random.Next(min, max);

Hi,
I have a method which produces a random DNA sequence. I would like to
write a unit test for it, but can't quite figure out what makes sense. It is
easy to test that a DNA sequence is produced. What I can't figure is
randomness. By it's very nature random is random. I have written a simple
test that generates 500 sequences and checks that none of them are the same.
That works, but seems very weak besides, if the sequences are truly...

What is the correct method for generating 2 independent random numbers?
They will be compared whether they are equal.
What about this method:
srand(time(0));
int r1 = rand();
srand(rand());

bool f = r1 == r2;

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
