#!/usr/bin/perl -w
#output the largest number from a file
$max_number = &max(3,5,10,4,6) ;
sub max
{
my($max_sofar_number) = shift @_ ;
foreach (@_)
{
if($_ > $max_sofar_number)
{
$max_sofar_number = $_ ;
}
}
$max_sofar_number ;
}
print "The largest number is $max_number \n";
以上代码是计算多个数的最大数,感觉和C的写法简单了不少,真乃浓缩的是精华..
