Count up
Problem
Start with my $n = 9;. The postfix ++
operator has a subtle feature: as an expression it returns the value the
variable held before the increment, then bumps the
variable.
In a single say, print the result of $n++,
and on the next line print $n itself, so the difference is
visible.
Example
The program prints:
9
10
