Solution: Name length

Code

Here is the solution to the task:

my $first = prompt 'First name: ';
my $last  = prompt 'Last name: ';
say ($first ~ $last).chars;

🦋 You can find the source code in the file name-length.raku.

Output

Run the program and enter the two names.

$ raku exercises/strings/name-length.raku 
First name: Ada
Last name: Lovelace
11

Comments

We first concatenate the two names with the ~ operator and only then call the chars method on the result. The parentheses are important: without them, chars would be called on $last alone. Because we concatenate the names directly, with no space in between, the space is not counted — Ada (3) plus Lovelace (8) gives 11.
