The purpose of this project is to refresh your memories of programming since you took CSci 51, and to give students who took a different introductory courses a chance to get up to speed with Ada 95. Start working on this now, so you have a chance to ask questions about anything you don't understand!

Chapter 2 describes a package Currency and a child package Currency.IO, which together provide support for dealing with currency quantities in exact form, without the roundoff associated with floating point. Your tasks in this project are:

1. Compile the Currency and Currency.IO (currency-io.ads and currency-io.adb) files. These are packages; do not link them yet!
2. Read the Currency specification (currency.ads) and the body (currency.adb) very carefully. You will discover that several of the operations are "stubbed out", that is, they do not contain useful code yet. These are "under construction." Complete the construction of these operations; recompile till there are no compilation errors. This should be straightforward; use the code for other package operations as an example.
3. Write a very simple test program for these packages; use Test_Rationals_1 as an example. The goal here is just to make sure you know how to compile and use the packages.
4. Now write a test plan for a program that determines whether all the currency operations are working properly. Use the test plan of Section 2.2 as an example; of course yours will be longer.
5. Finally, expand your test program so it implements your test plan. Run the program and compare its results with the plan.

What to submit:

You must submit listing (.lsb) files for the package specs and bodies, and one or more execution transcripts for the test program. Use the command turnin to set up a script session for your execution results. Also turn in your test plan. Be sure to indicate in your test results how they tie back into the plan. This can be done by annotating your test results by hand.
