I just need some suggestions on how to start this program I wanted to work on for practice.
I want to make a cash register program that gives change and only works with $1's, $5's, $10's, and $20's (I might add cents in later for more practice).
Change should always be made with the largest available denominations.
Here's an example of the output I want it to do.
Do you think Python or Java would be easier to do this in? I was also thinking about AWK or Bash? I am a beginner in all these languages.
I am an IT auditor with a big 4 accounting firm and am cur the process of conducting an application program change audit for a large public company related to Sarbanes Oxley. This is my first time using this forum and need some assistance in verifying a fact that I believe to be true.

apache::reload
Apache::Reload(3) User Contributed Perl Documentation Apache::Reload(3)NAME
Apache::Reload - Reload changed modules
SYNOPSIS
In httpd.conf:
PerlInitHandler Apache::Reload
PerlSetVar ReloadAll Off
Then your module:
package My::Apache::Module;
use Apache::Reload;
sub handler { ... }
1;
DESCRIPTION
This module is two things. First it is an adaptation of Randal Schwartz's Stonehenge::Reload module that attempts to be a little more
intuitive and makes the usage easier. Stonehenge::Reload was written by Randal to make specific modules reload themselves when they
changed. Unlike Apache::StatINC, Stonehenge::Reload only checked the change time of modules that registered themselves with
Stonehenge::Reload, thus reducing stat() calls. Apache::Reload also offers the exact same functionality as Apache::StatINC, and is thus
designed to be a drop-in replacement. Apache::Reload only checks modules that register themselves with Apache::Reload if you explicitly
turn off the StatINC emulation method (see below). Like Apache::StatINC, Apache::Reload must be installed as an Init Handler.
StatINC Replacement
To use as a StatINC replacement, simply add the following configuration to your httpd.conf:
PerlInitHandler Apache::Reload
Register Modules Implicitly
To only reload modules that have registered with Apache::Reload, add the following to the httpd.conf:
PerlInitHandler Apache::Reload
PerlSetVar ReloadAll Off
# ReloadAll defaults to On
Then any modules with the line:
use Apache::Reload;
Will be reloaded when they change.
Register Modules Explicitly
You can also register modules explicitly in your httpd.conf file that you want to be reloaded on change:
PerlInitHandler Apache::Reload
PerlSetVar ReloadAll Off
PerlSetVar ReloadModules "My::Foo My::Bar Foo::Bar::Test"
Note that these are split on whitespace, but the module list must be in quotes, otherwise Apache tries to parse the parameter list.
Un-Register Modules Explicitly
If ReloadAll is set to On, then you can explicity force a module not to be reloaded with
no Apache::Reload;
A warning will appear in the error log that the file has changed, but will not be reloaded
Special "Touch" File
You can also set a file that you can touch() that causes the reloads to be performed. If you set this, and don't touch() the file, the
reloads don't happen. This can be a great boon in a live environment:
PerlSetVar ReloadTouchFile /tmp/reload_modules
Now when you're happy with your changes, simply go to the command line and type:
touch /tmp/reload_modules
And your modules will be magically reloaded on the next request. This option works in both StatINC emulation mode and the registered
modules mode.
PSUEDOHASHES
The short summary of this is: Don't use psuedohashes. Use an array with constant indexes. Its faster in the general case, its more
guaranteed, and generally, it works.
The long summary is that I've done some work to get this working with modules that use psuedo hashes, but its still broken in the case of a
single module that contains multiple packages that all use psuedohashes.
So don't do that.
