| Jun 16, 2022 at 18:08 | comment | added | guitarpicva | @Parham, sadly this also seems to skip empty fields, such as: ` a,b,c,,,f,g` Which returns a b c f g as the 5 members of the vector instead of including the empty strings. Indexed content suffers. :( It is pretty common in things such as NMEA GPS sentences to have multiple empty fields in it's indexed, character separated string data. | |

| Aug 10, 2021 at 5:50 | comment | added | HMartyrossian | I voted "Up" for Parham's solution and modified it a bit: std::vector<string> tokenize(const std::string& str, const string& delimiters) { std::vector<string> result; size_t start = str.find_first_not_of(DELIMITER), end = start; while (start != std::string::npos) { // Find next occurrence of delimiter end = str.find(DELIMITER, start); // Push back the token found into vector result.push_back(str.substr(start, end - start)); // Skip all occurrences of the delimiter to find new start start = str.find_first_not_of(DELIMITER, end); } return result; } | |
