Your regex is: /^\d+$/ , which means:
- any numeral (\d)
- at least one time (+)
- but nothing else in that line (surrounded by ^$)
So your code is:
if ($var!~/^\d+$/) {
print "You entered letters of the alphabet please try again :)";
} else {
print "U entered only digits... WELL DONE!";
}
For more information on regular expressions in perl,
have a look at man perlre and perlfaq6.
