hi all

this is my first post to this group.
i have just started learning perl and
i am really amazed to find (infact couldn't find) that no keywords like
'true' or 'false' exist for perl. as we see in C/C++ etc.
experts please ensure me if i am right?

thanks for your time

The name of the language is Perl.

C does not have keywords true and false.

You might want to head on over to <http://learn.perl.org/> for resources
for beginners.

Welcome aboard. If you haven't done so already, please have a look at the
posting guidelines that appear here often. No, you haven't done anything
wrong, that's just a generic comment.

Well, you're right about Perl - it doesn't have 'true' or 'false' keywords.
C++ does, but C doesn't. C99 defines them as macros.

In C/C++, zero is false, non-zero is true. A NULL pointer is zero, so any
string is true. In Perl, as stated in 'perldoc perlsyn', "The number 0, the
strings '0' and '', the empty list (), and undef are all false in a boolean
context. All other values are true."
