      #include <regex>#include <iostream>   int main(){try{std::regex re("[a-b][a");}catch(const std::regex_error& e){std::cout<<"regex_error caught: "<< e.what()<<'\n';if(e.code()==std::regex_constants::error_brack)std::cout<<"The code was error_brack\n";}}

      Résultat : 

      regex_error caught: The expression contained mismatched [ and ]. The code was error_brack
