Re: Different way of getting Standard input

Hi All,

Hello,

What is the difference in Accepting the following form of standard input?

1) $a = <STDIN>;

readline() from the standard input device in scalar context.


2) $b = <stdin>;

Same as 1 but using the deprecated lower case form of STDIN.


3) $c = <>;

readline() from the files in @ARGV or if @ARGV is empty then readline() from STDIN.


Now check,
print $a $b $c;


What is actually happening?
Will this be written to some standard input file?

There is no "standard input file".


If so In windows where this will be written?

print() without an explicit filehandle will print to the currently selected filehandle, which by default is STDOUT.
