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
