post code things you find interesting. i am learning perl and there is some things that are quite cool like things restore after loop control. #!/usr/bin/perl $num = 6; foreach $num (1,2,3,4){ print "$num "; } print $num; #this will print 6 as perl will restore the variable used after the for loop. and there is a defualt value $_ that has a lot of use. values in a foreach values of a array are the actual elements even if they are primitive #!/usr/bin/perl @nums = (1, 2, 3, 4); foreach (@nums){ $_++; } print "@num\n"; # this will print 2 3 4 5 - and parentheses are optional another with the special varable is. #!/usr/bin/perl @nums = (1, 2, 3, 4); foreach (@nums){ print(); #will use the $_ when thjere is no arguments. }
