建立哈希，访问哈希

%friend=('fred'=>flintstone,'barney'=>rubble,'wilma'=>flintstone,);#构建哈希
print "Please input second name,and you will get the family namen";
chomp($second_name=<>);#又一次忘记写chomp了
$family_name=$friend{$second_name};#哈希的取值
print "$family_name";

结果如下：

F:&;perla.pl
Please input second name,and you will get the family name
fred
flintstone
F:&;
