The classical introductory exercise. Just say "Hello, World!".
"Hello, World!" is the traditional first program for beginning programming in a new language or environment.
The objectives are simple:
If everything goes well, you will be ready to fetch your first real exercise.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
#!/usr/bin/env perl
use Test2::V0;
use FindBin qw<$Bin>;
use lib $Bin, "$Bin/local/lib/perl5"; # Find modules in the same dir as this file.
use HelloWorld qw(hello);
plan 2; # This is how many tests we expect to run.
imported_ok qw<hello> or bail_out;
# Run the 'is' sub from 'Test2::V0' with three arguments.
is(
hello(), # Run the 'hello' sub imported from the module.
'Hello, World!', # The expected result to compare with 'hello'.
'Say Hi!' # The test description.
);
# Declare package 'HelloWorld'
package HelloWorld;
use strict;
use warnings;
use Exporter qw<import>;
our @EXPORT_OK = qw<hello>;
sub hello {
'Hello, World!'
}
1;
A huge amount can be learned from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
Level up your programming skills with 3,450 exercises across 52 languages, and insightful discussion with our volunteer team of welcoming mentors. Exercism is 100% free forever.
