Auto print a new line in Perl

In Perl, just have print function, where is the println func. similarly in C++ ? Perl doesn’t have one! Help!

google: perl println -> Perl’s Special Variables

From there they show us to make it available by adding our own function :

  sub println {
local $\ = "\n";
print @_;

The main idea is $\ is a special system variable that auto add to the end of the string printed by command print.
Since then, enjoy the convenient from : println "Ur text goes…" !
