hello,
Is there any alternative of rand() function i.e i mean any source
avilable to perform same as rand()without using any built in function,
plz reply,
thanks in advance,

Of course there is. Do some reading about random number generators,
pick an algorithm you'd like to try, learn a programming language,
then implement the algorithm.
If you're looking for a ready-made function, try a google search on
"PRNG source" or "random number generator source."

There are many alternatives. You can use www.google.com to search for
them on the Web, or groups.google.c om to search for both links and code
that have been posted to this newsgroup.

Bullshit. It is such a common courtesy phrase that it even has a

Can any tell me why rand() is such a bad pseudo-random number generator.
In all the articles I have read they say that you can predict the outcome
of rand() but when I used its output with NIST's random number testsuite
it passed all of the tests thrown at it for randomness. Can anyone
suggest a test I could use that it would fail? A pointer to a suitable
article would be appreciated.
Thanks for your help in advance,
Tom

Hi,
I'm developing a simple application which uses rand() frequently, and
I was just wondering if there are any alternatives to generating random
numbers other than the in-built function in C? I'm using GNU C/C++
compiler 3.3.1.
rand() works okay for me, but I suppose it has its limitations?

When I use rand(), is the RAND_MAX value how long I am guaranteed that
the same value will not appear twice?
And is this a floating window?
For example, if RAND_MAX is 32767, and I make 500,000 consecutive rand
calls then is the rand() algorithm going to guarantee me that no
floating window of calls over that 500,000 rand calls will have the
same value twice? The only way that would work is if the series was
identical everytime.

Hi all,
I'm writing a shell language in c++ that supports the generation of
random numbers, and by its nature, each command must be executed in a
new thread. The call to the random function from my language simply
propogates up to the rand( ) function from c++. For some reason, C++
will give each thread independent use of their own rand( ) function, so
that a rand( ) call from one thread won't affect another thread's call
to rand( )....

Hi all,
rand() is not thread safe, a fact that may not be so bad after all..
However, I face the following problem: a piece of code uses rand() to
get a random sequence, but always seeds with the same seed for
reproducibility of the results. Now I am porting this (old C89) code
and have setup a nice app with threads that drives on one thread the
old code and on another the new code, so that I can compare the
results and see that nothing...

Hi,
I've found several sites on google telling me that I shouldn't use
rand() % range+1
and I should, instead, use something like:

Quick rand() question:
I know you're not supposed to use "rand() % 1024" for instance,
because it focuses on the lower bits. However, it seems to me that
given that the argument is not a power of two (or near a power of
two), that this is not an issue. The upper bits will participate
equally in the result with the lower. Am I missing something?
Thanks!

Hello folks,
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.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
