Hi All,
What is the difference in Accepting the following form of standard input?
1) $a = <STDIN>;
2) $b = <stdin>;
3) $c = <>;
Now check,
print $a $b $c;
What is actually happening?
Will this be written to some standard input file?
If so In windows where this will be written?
Thanks,
Prabu.M.A

3 diffrent way of writing the same thing, a lot of time PERL have more
than one way of doing things.
I have learn to write
<STDIN> upper letters to show it is a stream
You have 3 standard streams (without open anything)
a. STDIN (Defaults reads from keybord
b. STDOUT (Default write to the screen)
c. STDERR (Defaults write to the screen to)
STDOUT and STDERR have a mening that you allways write errormessage to
STDERR and can
redirect it to eg. a errorfile.
IF you haven't redirect STDIN it reads from KEYBORD to MEMORY and
don't give you any file
that you can use, if you like to save data open a file and write alla
data to it
