Hi Monks,
My annoying problem is: I am looping through an array of @numbers
from 1-50 with some numbers missing. I am comparing these numbers
to that of a $counter, if the two numbers are equal, I want to print an image to the screen,
if the two numbers are different e.g. $counter = 10, number = 9, i print a different image.
My problem is occuring after a missing number has been found, I am struggling to get the counter
to catch up with the number - I have tried +=1 and all sorts but my efforts mean that the wrong image is printed after the missing number (because the right image
is only printed when the numbers are equal). How can I change this to still print one of the images after a missing number has been found??
Hopefully some code will explain this:
Thanks a lot.
for my $counter ( 1..100 ) {
for my $i ( @numbers ) {
my $img;
print "WELL: $i <P> GOAL: $counter<P>";
if ($i == $counter) {
$img = $right[$counter-1];
}
else {
$img = "error.bmp";
$i -= 1;
}
$counter++;
print qq(<area href="http:///cgi-bin/$img"
>);
}
}
