Course of Raku / Essentials / Strings / Exercises / Hello, Concatenation!

Solution: Hello, Concatenation!

Code

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.

Output

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!

Comments

Compare the program with the previous variant where we passed three strings to the say routine:

say 'Hello, ', $name, '!';

This time, the three parts are first concatenated and then passed to say as a single string.
