In Perl, you can concatenate strings using the dot (.) operator. Here's an example:
my $str1 = "Hello";
my $str2 = "World";
my $str3 = $str1 . " " . $str2;
print $str3;
Output:
Hello World
In the above example, we first created two separate string variables, $str1 and $str2. We then used the dot operator to concatenate them together and store the result in a third variable $str3. Finally, we printed out the resulting string $str3.
You can also concatenate strings along with other data types. Here's an example:
my $name = "John";
my $age = 30;
my $str = "My name is " . $name . " and I am " . $age . " years old.";
print $str;
Output:
My name is John and I am 30 years old.
In this example, we concatenated string variables $name and $age along with some text to create the final string $str.
