Hello Ron,
> for($i; $i < $n; $i++)
When Perl evaluates the initialiser of the for loop, it just sees a `$i`.
There are no effects for such a statement. Hence the warning. For getting more
details about warnings, you can use the diagnostics pragma. (See `perldoc
diagnostics`)
Since you have already initialised $i to 0 (my $i = 0;), you could omit the
initialiser of the for loop:
for ( ; $i < $n; $i++ )
Otherwise, as is normal, you can use the for loop's initialiser section to
declare and then initialise $i to 0:
for ( my $i = 0; $i < $n; $i++ )
Your program can be rewritten as:
print join ', ', 0 .. 7;

Alan Haggai Alavi.
