1. Print Array - 打印数组

&print_array("数组")

#!/usr/bin/perl -w 
 
use strict;
use Data::Dumper;
 
# Debug Switch
my $debug = 0;
 
sub print_array {
        my @array = @_;
        my $index;
        for ( $index = 0; $index < @array; $index++ ) {
                print "$array[$index] \n";
        }
}
 
# 测试
my @test = (1,2,3,4,5,6,7,8,9,0);
&print_array(@test);

#!/usr/bin/perl -w 
 
use strict;
use Data::Dumper;
 
# Debug Switch
my $debug = 0;
 
sub print_array {
        my @array = @_;
        foreach my $tmp (@array) {
                print "$tmp \n";
        }
}
 
# 测试
my @test = (1,2,3,4,5,6,7,8,9,0);
&print_array(@test);

2. Print Hash - 打印哈希

&print_hash("哈希")

#!/usr/bin/perl -w 
 
use strict;
use Data::Dumper;
 
# Debug Switch
my $debug = 0;
 
sub print_hash {
        my %hash = @_;
        while ( my ($key, $value) = each %hash ) {
                print "$key => $value\n";
        }
}
 
# 测试
my %test = (a=>1, b=>2, c=>3);
&print_hash(%test);

3. Last Digits - 取字符串后"n"位

&last_digits("字符串", "位数")

#!/usr/bin/perl -w 
 
use strict;
use Data::Dumper;
 
# Debug Switch
my $debug = 0;
 
sub last_digits () {
        my $string = shift;
        my $digits = shift;
        my $length = length($string);
        if ($length > $digits) {
                print substr($string, $length - $digits, $digits);
        }
}
 
# 测试
&last_digits("987654321", "3");
