Computer Programming

Getting started with Perl

1. Accessing the Perl Programming Environment.
2. Editing the Perl source code.
3. General Perl CLI tutorial - to follow. 5^th year and IT PLC use this instead.
4. Using Perl online.

Perl Programming & Assignments

• Nuggets:
1. Formatting numeric output
2. Killing your program quickly
3. Indentation
4. Formatting a receipt
5. Creating a web input form
6. Using Term::Screen to control your screen output and keyboard input
7. The official Term::Screen test file - from which you can learn how to use the module components

Perl Tutorials:

• Learning Perl
• Perl in a Nutshell (the 'official' book)
• Programming Perl
• Advanced Perl Programming
• Perl Cookbook
• Learning Perl on Win32
• Perl for System Administration"

Flowchart Tutorials (verrrry important):

• Basic rules.
• Tutorial #01
• Tutorial #02
• Tutorial #03
• FGI

Other Tutorials:

• On-line version of Powerpoint Presentation on General Programming (Read This One At Least Once!)

  • www.physics.drexel.edu
  • The Guide2C book companion site (well worth visiting), particularly the internet resources page.

General items:

• An interesting story.
• NB >>>  For ANSI console control look here. ANSI codes can be exceptionally useful in improving the appearance of your program on screen, and thus gaining marks in programming assignments! (C formatted)

Assessment 2007/8:

• Written Exam 40%
• Written Exam 2008
• Solutions to 2008 Written Exam
• Assignments: (2 @ 30% each = 60%)

For each assignment submit:

1. Standard Cover Sheet
2. Program Listing
3. Flow Chart (should be completed first)
4. Screen shots of sample program runs etc
5. Any other appropriate items in support of your assignment

• Assignment #1, Option 1: Perl CGI program to verify user input - Tour Booking. Cross reference to Web Authoring
• After a sanity check on the user input data the following criteria to a booking will apply:
1. No booking for in excess of the guide figure from the form may be made.
2. No booking for less than 10 people may be made
3. Bookings may only be made for the following month.
4. Bookings of children only are not acceptable.
5. The completed booking should be stored in the file ">> /home/public/fitzgerald2008.dat"
6. Write the record of the booking as a series of fields (even if empty) separated by colons (:) as the delimiter
7. Concatenate all the data with the '.' operator
8. The first item in the record should be your username.
• Sample Tour Booking Form with functioning script.
• Use the name "bookings.html" for the HTML file containing your version of the booking form.
• Booking forms so far:
1. it.lilietea
2. it.susanc
3. it.johnc
4. it.jamiec
5. it.peterg
6. it.fionak
7. it.kieranob
8. it.rhondaw


• View the tour bookings database.
• Assignment #1, Option 2: - Barcode Shopping Reader Program (Assignment #1 from 2006/7).
• Assignment #2, Option 1: - Maze Game. (Almost) identical to the 4^th assignment from 2000.
  • For an example of how this program might work in actuality, log in to the programming server and change directory to /home/public - within that folder is a pre-compiled binary of a C program that largely does as this years assignment is required to do. The file is called amazing.bin and can be directly executed within that directory using the command ./amazing.bin - your character is the @ symbol. If you have read the brief you'll know the meaning of the other symbols, as well as the purpose of the program.
  • Please use the Term::Screen module for this program.
  • Sample Steps:
  1. 0401.pl ("Hello World" using Term::Screen)
  2. 0402.pl (put a map on the screen quickly: uses file maze04.map)
  3. 0403.pl (control the position of a character on screen)
  4. 0403.pl.txt (doing position checking in the maze)
  5. 0404.pl (faulty!)
  6. 0405a.pl (corrected use of 2D array: uses file maze06.map)
• Assignment #2, Option 2: - Bomb Defuser Game (FKA 'hangman'). Details to follow.
  • Please use the Term::Screen module for this program.

Assessment 2006/7:

This years assessment structure will not vary from that of previous years. However, the language taught is to change again. Once we programmed in a beautiful language called Pascal. Then we changed to C. Now we change again to a 'new' language: Perl (see above).
