Regex for unsigned integers. I am using flex -
i have tried code given on question (?<![-.])\b[0-9]+\b(?!\.[0-9]), flex shows: bad character: <
bad character: !
bad character: [

i'm not familiar flex rapid google search, appears flex uses < , > characters match tokens. try escaping these characters slash , see if helps.
