Address.plPerl的使用功能知名度
#!/usr/bin/perl
pacakge Address;
sub new {
my $package = shift;
my $self = {@_};
return bless $self, $package;
}
sub country {
my $self = shift;
return @_ ? ($self->{country} = shift) : $self->{country};
}
sub as_string {
my $self = shift;
my $string;
foreach (qw(name street city zone country)) {
$string .= "$self->{$_}\n" if defined $self->{$_};
}
return $string;
}
$test = Address-> new (
name => "Sam Gamgee",
street => "Bagshot Row",
city => "Hobbiton",
country => "The Shire",
);
test.pl
use Address;
$test = Address-> new (
name => "Sam Gamgee",
street => "Bagshot Row",
city => "Hobbiton",
country => "The Shire",
);
print $test->as_string;
它不能在test.pl 兩個perl的文件的在線使用地址找到地址是在同一個文件夾中。
我需要爲test.pl做些什麼才能看到Address.pl?
不要寫'沒有'use strict;使用警告;'。 – Quentin 2013-05-10 16:22:49
