Im new to C, and Im having a hard time getting a random number.
In bash, I would do something similar to the following to get a random number;

seed1=$RANDOM
seed2=$RANDOM
seed3=$RANDOM
SEED=`expr $seed1 * $seed2 / $seed3`
echo ${SEED%.*}
Now, in online examples... (4 Replies)

Hi,
How can I generate a string of random characters (alpha+numeric) of a particular length ?
For e.g. for
n=5, output = 'kasjf'
n=10, output = 'hedbcd902k'
Also, please let me know if random (valid) dates could also be generated.
Thanks (7 Replies)
Hi Guys and gals...
As you know I am getting to grips with POSIX and hit this stumbling block.
Generating two random numbers 0 to 255 POSIXly. Speed in not important hence the 'sleep 1' command.
I have done a demo that works, but it sure is ugly! Is there a better way?

Curses::Widgets::ProgressBar - Progress Bar Widgets
MODULE VERSION
$Id: ProgressBar.pm,v 1.103 2002/11/03 23:40:04 corliss Exp corliss $
SYNOPSIS
use Curses::Widgets::ProgressBar;
$progress = Curses::Widgets::ProgessBar->({
CAPTION => 'Progress',
CAPTIONCOL => 'yellow',
LENGTH => 10,
VALUE => 0,
FOREGROUND => undef,
BACKGROUND => 'black',
BORDER => 1,
BORDERCOL => undef,
HORIZONTAL => 1,
X => 1,
Y => 1,
MIN => 0,
MAX => 100,
});
$progress->draw($mwh);
$progress->input(5);
See the Curses::Widgets pod for other methods.
REQUIREMENTS
Curses
Curses::Widgets
DESCRIPTION
Curses::Widgets::ProgressBar provides simplified OO access to Curses-based progress bar. Each object maintains it's own state information.
Note that this widget is designed for rendering, not interactive input. The application should update the the value of the bar by either
calling the input method, which will add the passed value to the widget's current value, or by setting the value directly via the setField
method.
METHODS
new (inherited from Curses::Widgets)
$progress = Curses::Widgets::ProgressBar->({
CAPTION => 'Progress',
CAPTIONCOL => 'yellow',
LENGTH => 10,
VALUE => 0,
FOREGROUND => undef,
BACKGROUND => 'black',
BORDER => 1,
BORDERCOL => undef,
HORIZONTAL => 1,
X => 1,
Y => 1,
MIN => 0,
MAX => 100,
});
The new method instantiates a new Progress Bar object. The only mandatory key/value pairs in the configuration hash are X and Y. All oth-
ers have the following defaults:
Key Default Description
============================================================
CAPTION undef Caption superimposed on border
CAPTIONCOL undef Foreground colour for caption text
LENGTH 10 Number of columns for the bar
VALUE 0 Current value
FOREGROUND undef Default foreground colour
BACKGROUND undef Default blackground colour
BORDER 1 Display border around the set
BORDERCOL undef Foreground colour for border
HORIZONTAL 1 Horizontal orientation for bar
MIN 0 Low value for bar (0%)
MAX 100 High vlaue for bar (100%)
Setting the value will change the length of the bar, based on the bounds set with MIN and MAX. The CAPTION is only rendered on the border
of a horizontal progress bar.
draw
$progress->draw($mwh);
The draw method renders the progress bar in its current state. This requires a valid handle to a curses window in which it will render
itself.
input
$progress->input(5);
The argument is added to the progress bar's current value.
