1 Concatenate Strings in Array with join Function

In this example,

We create an array `@words` with strings.
We use the `join` function to concatenate strings in the array with a space separator.
We print the concatenated string.

Perl Program

@words = ("Hello", "World", "!");
$concatenated = join(" ", @words);
print "Concatenated String: $concatenated\n";

Output

Concatenated String: Hello World !

2 Concatenate Strings in Array with Loop

In this example,

We create an array `@words` with strings.
We initialize an empty string `$concatenated`.
We use a loop to iterate through the array and concatenate each element to `$concatenated`.
We print the concatenated string.

Perl Program

@words = ("Hello", "World", "!");
$concatenated = "";
foreach $word (@words) {
    $concatenated .= "$word ";
}
print "Concatenated String: $concatenated\n";

Output
