How does Perl internally store a string

curiousmaverick

Hello friends,

How does Perl internally store a string?Like in many languages a String is a memory address that references an array of characers. That array is typically terminated with a null.Is it the same here?

In that case while checknig a string, do we need use for both i.e. empty string as well as null?

Regards,
Mav

It depends as how you have defined as varaible:

-- my $var = "";
-- my $var;
-- my $var = undef;

Check your case and provide the info.
