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

Solution: Hello, Interpolation!


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-interpolation.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 continues and prints the greeting:

$ raku exercises/strings/hello-concatenation.raku
What is your name? Raku
Hello, Raku!


Notice that this time, the string is double-quoted. In double quotes, variables are interpolated, so their content is placed in the string.
