REQ. Program texts

REQ. Program texts

[Kelvin Pope]

I hope some one can help me out on this one.  As part of a project I
have got to explain ADA to a group of colleagues & to do this I thought
it would be best to demonstrate a few programs.  What I am looking for
is the text for the following programs that we can enter in a text
editor and hopefully get to run.

1	A program to display the minimal set of notes and coins to make
	up a particular amount of money.  This will hopefully include a
	procedure to slim down the code with all the repetive actions
	that would take place.

2	A program to use the ROT-13 cipher, so that any word/s entered
	would be replaced by letters thirteen places ahead of them in the
	alphabet.

3	A program to read text from a file & count the number of
	occurrences of each letter of the alphabet, with a table
	entirely visible on the screen at one time.  Upeer & lower case
	letters should be treated the same.

4	A program that declares an enumeration type to represent months
	of the year which prompts the user to enter a date & then
	diplays a message indicating if it is valid or not.  This would
	include leap years.


I would be eternally grateful of any help with these programs that
anybody could give me.

Thanks in advance,

Kelvin.
