Solution: Greet a person

Here is a possible solution to the task.

Code

my $name = prompt 'What is your name? ';
say 'Hello, ', $name, '!';

🦋 You can find the source code in the file greet-a-person.raku.

Output

Run the program and enter a name when you get the prompt:

$ raku exercises/scalar-variables/greet-a-person.raku 
What is your name? Inge
Hello, Inge!

Comments

1. This program uses a scalar variable $name to keep a string that was entered by the user in response to the prompt. When the variable is used in the list that you pass to the say routine, you get the name in a message.

2. There is a better way to solve this problem using string interpolation. Let us return to this problem shortly.
