Quiz — Posftix for*
Try to complete the program so that it uses the postfix form of
for and prints the following text:
A
A
B
B
C
CHere is the draft of the code:
| . | |
| { | ␣ |
| . | .say; |
| . | .say; |
| } | ␣ for 'A'..'C'; |
This code is an example of using a code block with the postfix
for. Note that for must appear on the same
line as the closing curly brace. If you put it on a new line, the block
will be separated from the loop, and you get a compilation error:
Missing block. It’s probably better to avoid such practice
of using a code block with postfix constructs.
