IMPORTANT:
This sample was originally intended as an exercise for the ICU Workshop (September 2000).
The code currently provided in the solution file is the answer to the exercises, each step can still be found in the 'answers' subdirectory.

Day 2: September 12th 2000
Pre-requisites:
1. All the hardware and software requirements from Day 1.
2. Attended or fully understand Day 1 material.
3. Read through the ICU user's guide at

#Date/Time/Number Formatting Support
9:30am - 10:30am
Alan Liu
Topics:
1. What is the date/time support in ICU?
2. What is the timezone support in ICU?
3. What kind of formatting and parsing support is available in ICU, i.e.
NumberFormat, DateFormat, MessageFormat?
INSTRUCTIONS
------------
This exercise was first developed and tested on ICU release 1.6.0, Win32,
Microsoft Visual C++ 6.0. It should work on other ICU releases and
other platforms as well.
MSVC:
Open the file "msgfmt.sln" in Microsoft Visual C++.
Unix:
- Build and install ICU with a prefix, for example '--prefix=/home/srl/ICU'
- Set the variable ICU_PREFIX=/home/srl/ICU and use GNU make in
this directory.
- You may use 'make check' to invoke this sample.
PROBLEMS
--------
Problem 0:
Set up the program, build it, and run it. To start with, the
program prints out the word "Message".
Problem 1: Basic Message Formatting (Easy)
Use a MessageFormat to create a message that prints out "Received
<n> argument(s) on <d>.", where n is the number of command line
arguments (use argc-1), and d is the date (use Calendar::getNow()).
HINT: Your message pattern should have a "number" element and a
"date" element, and you will need to use Formattable.
Problem 2: ChoiceFormat (Medium)
We can do better than "argument(s)". Instead, we can display more
idiomatic strings, such as "no arguments", "one argument", "two
arguments", and for higher values, we can use a number format.
This kind of value-based switching is done using a ChoiceFormat.
However, you seldom needs to create a ChoiceFormat by itself.
Instead, most of the time you will supply the ChoiceFormat pattern
within a MessageFormat pattern.
Use a ChoiceFormat pattern within the MessageFormat pattern, instead
of the "number" element, to display more idiomatic strings.
EXTRA: Embed a number element within the choice element to handle
values greater than two.
ANSWERS
-------
The exercise includes answers. These are in the "answers" directory,
and are numbered 1, 2, etc.
If you get stuck and you want to move to the next step, copy the
answers file into the main directory in order to proceed. E.g.,
"main_1.cpp" contains the original "main.cpp" file. "main_2.cpp"
contains the "main.cpp" file after problem 1. Etc.
Have fun!
