Why do I get two different results while using sregex_iterator with a regex variable pattern vs a constructed pattern

it fixes the issue If I input "110110" in to the application, the first chunk prints out "1" while the second chunk prints out "2". , C++14 fixed the interface by deleting the constructor:
code :
regex_iterator(BidirIt, BidirIt,
               const regex_type&&,
               std::regex_constants::match_flag_type) = delete;

How to interpolate a variable into a regex-pattern in the regex part of a substitution?

it should still fix some issue The problem is that interpolating a regex into another regex via the <$regex> syntax will not install a result in the match variable. There's two ways to get around this:
The easiest way is to just use the regex directly in subst, i.e. $str .= subst($regex, { $0 }); Give the interpolated regex an explicit name and access the result via that, i.e. $str .= subst( / /, { $[0] });

Is is possible to create regex pattern for comma-separated list without repeating pattern for single item?

it helps some times You can shorten it and improve the readability by using \w for "letters+underscores+numbers", use \d for numbers, and turn on case insensitive matching so you can just use a-z for letters:
