In Perl, data can be gotten from a user and stored in a variable or hash. This is done using the <STDIN> command.

Below is a code to get user input and store in a variable:

Program/Source Code:

File name: index.pl

#Getting data from a user in Perl

print "what is your name? \n";
$x = <STDIN>;

print "Welcome Mr $x";

Output:

what is your name?
Godwill
Welcome Mr Godwill

The user input could also be assigned to a hash or array by simply replacing the variable with a hash or array. Doing this will give the user the possibility to add multiple data inputs since arrays and hashes don't only store one value. For Example;

#Gettings data from a user in Perl

print "what is your name? \n";
@x = <STDIN>;

print "@x";

Output:

what is your name?
Godwill
Tetah

Since the output runs on a command line, use the command for your platform equivalent to Ctrl + C on windows to the list input.
