Question
How will you convert an array to string
Answers
join() function joins the separate strings of LIST into a single string with fields separated by the value of EXPR, and returns the string.

join EXPR, LIST

Following is the example −

#!/usr/bin/perl

# define Strings
$var_string = "Rain-Drops-On-Roses-And-Whiskers-On-Kittens";
$var_names = "Larry,David,Roger,Ken,Michael,Tom";

# transform above strings into arrays.
@string = split('-', $var_string);
@names = split(',', $var_names);

$string1 = join( '-', @string );
$string2 = join( ',', @names );

print "$string1
";
print "$string2
";
print "$string[3]
"; # This will print Roses
print "$names[4]
"; # This will print Michael

This will produce the following result −

Rain-Drops-On-Roses-And-Whiskers-On-Kittens
