Description
Perl is a modern general purpose programming language developed by linguist Larry Wall. (Trivia -- Wall trained with Summer Institute of Linguistics, just like Drs. Chase, Rohrbaugh, and Owen :-).
In this lab you will familiarize yourself with Perl and write some simple programs. As you become more familiar with the features of Perl, it will be a useful backdrop for our conversations about programming language syntax and semantics.
Perl has already been installed on the F366 lab computers. To run a Perl program, type your code in a text file (e.g., using notepad), and save with the suffix *.pl. Here's an example:
Once it is saved, you can run the program by opening a command line window to the location where you saved it, and run it by typing perl filename.pl
Try it yourself!
Before proceeding, I'd like to provide the following as a 'coding template' -- please use this as the basis for any Perl program you write for this class.
#!/usr/bin/perl # @file filename.pl # @author First Last # @version 1.0
use strict; use warnings; use feature ':5.10';
Now that we've gotten the preliminaries out of the way, we can proceed. To introduce Perl, we'll use the following tutorials by Doug Sheppard:
- Beginner's Introduction to Perl 5.10 ; also consult www.ebb.org/PickingUpPerl/pickingUpPerl_2.html
After you complete this part of the tutorial, write a Perl program to print an investment report. Prompt the user for balance, interest rate, and number of months; then print out a table similar to the following. I've also provided an excel workbook demonstrating an investment report.
Investment Parameters --------------- Initial Balance: $100000.00 Rate (APR): 5.5% Term in Months: 48 Month Init Bal Int Earned End Bal ----- -------- ---------- -------- 1 10000.00 54.17 10054.17 2 10054.17 54.46 10108.63 3 10108.63 54.76 10163.38 ...
Turn in the following:
- Incremental releases (at least 2 early releases in addition to the final):
- all code properly commented
- all code compiles & runs without error
- each release implements incremental functionality .
- screenshot(s) of successful runs
- RELEASE_NOTES.txt updated and included with each release
- A lab report that describes your development steps and explains choices you made along the way
