Re: printing all elements of arrays

(I)s there any way to print all the elements of any array instead of referencing each element like so [0], [1], [2] ...etc?

If you want to print out each element of an array on its own line,

print join("\n", @array), "\n";
[download]

is probably the easiest way to do it. If the extra "\n" offends you,

print map {$_ . "\n"} @array;
[download]

will do much the same thing, but it's less idiomatic (I think).

I like `print join("\n", @array, "")`, myself.	[reply] [d/l]

what does the print map state? Okay, `print join("\n", @array), "\n";` [download] says "Stick a newline between each element in `@array`, return that as a string, print it, and print a newline at the end." On the other hand, `print map {$_ . "\n"} @array;` [download] says "Build a list whose elements are the elements of `@array` with "\n" appended to them, then print that list." what perldoc can I read about the map call? You can read about any function with `perldoc -f func_name`. `-- F o x t r o t U n i f o r m Found a typo in this node? /msg me % man 3 strfry`	[reply] [d/l] [select]

Here is another way to print the elements of an array on separate lines, using the `$,` variable (see perlvar: `#!/usr/bin/perl use strict; use warnings; my @array = (1..10); local $, = "\n"; print @array;` [download]	[reply] [d/l] [select]

perldoc -f map. map is a list-transformer; you give it a block of code and a list, and it applies the code to each element of the list, and returns a list made up of what the code returned for each element.	[reply]

You can read perlfunc to find out about map. Also, the easiest way to print all the elements of an array is: `print "@array\n";`	[reply] [d/l]
