Solution: Hello, Concatenation!
Here is a possible solution to this problem:
my $name = prompt 'What is your name? '; say 'Hello, ' ~ $name ~ '!';
🦋 You can find the source code in the file hello-concatenation.raku.
Run the program, and it will enter a mode when it waits for your input. After you type the name and press Enter, the program goes on and prints the greeting:
$ raku exercises/strings/hello-concatenation.raku What is your name? John Hello, John!
Compare the program with the previous variant where we passed three strings to the
say 'Hello, ', $name, '!';
This time, the three parts are first concatenated and then passed to
say as a single string.
