Strings

Working with Strings

Perl has two kinds of string literals:

Double-Quoted Strings

Double-quoted strings interpolate variables and escape sequences:

my $name = "World";
say "Hello, $name!";     # Hello, World!
say "Tab:\there";        # Tab:	here
say "Newline:\n";        # prints a newline

Single-Quoted Strings

Single-quoted strings are literal -- no interpolation:

say 'Hello, $name!';     # Hello, $name!  (literally)

String Concatenation

The dot . operator concatenates strings:

my $full = "Hello" . ", " . "World!";
say $full;   # Hello, World!

String Repetition

The x operator repeats a string:

say "ha" x 3;   # hahaha

String Functions

say uc("hello");        # HELLO
say lc("HELLO");        # hello
say length("Perl");     # 4

Your Task

Create two variables $first and $last, concatenate them with a space, and print the full name.
