[edit]Example
Run this code
#include <iostream>#include <regex> 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";}}
Possible output:
regex_error caught: The expression contained mismatched [ and ].The code was error_brack
