Adapted example from boost::regex
The attached code is adapted from the credit_card.cpp example of boost::regex.
When compiled using boost::regex
g++ -std=c+11 -DBOOST credit_card.cpp -lboost_regex
the output is as expected:
machine_readable_card_number("0000111122223333") returned 0000111122223333
machine_readable_card_number("0000 1111 2222 3333") returned 0000111122223333
machine_readable_card_number("0000-1111-2222-3333") returned 0000111122223333
machine_readable_card_number("000-1111-2222-3333") returned 000111122223333
human_readable_card_number("0000111122223333") returned 0000-1111-2222-3333
human_readable_card_number("0000 1111 2222 3333") returned 0000-1111-2222-3333
human_readable_card_number("0000-1111-2222-3333") returned 0000-1111-2222-3333
human_readable_card_number("000-1111-2222-3333") returned 000-1111-2222-3333
but when compiled with std::regex then std::regex_replace simply returns the
same string it is given:
g++ -std=c++11 credit_card.cpp
machine_readable_card_number("0000111122223333") returned 0000111122223333
machine_readable_card_number("0000 1111 2222 3333") returned 0000 1111 2222
3333
machine_readable_card_number("0000-1111-2222-3333") returned
0000-1111-2222-3333
machine_readable_card_number("000-1111-2222-3333") returned 000-1111-2222-3333
human_readable_card_number("0000111122223333") returned 0000111122223333
human_readable_card_number("0000 1111 2222 3333") returned 0000 1111 2222 3333
human_readable_card_number("0000-1111-2222-3333") returned 0000-1111-2222-3333
human_readable_card_number("000-1111-2222-3333") returned 000-1111-2222-3333
