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
