而在C++的正则中,把这种操作称为Tokenize,用模板类regex_token_iterator<>提供分词迭代器,依旧通过例子来看: 1std::stringmail("123@qq.vip.com,456@gmail.com,789@163.com,abcd@my.com"); 2std::regexreg(","); 3std::sregex_token_iteratorpos(mail.begin, mail.end, reg, -1); 4decltype(pos) ...
void tokenize(const string& str, vector<string>& tokens, const string& delimiters = ",") { // Skip delimiters at beginning. string::size_type lastPos = str.find_first_not_of(delimiters, 0); // Find first non-delimiter. string::size_type pos = str.find_first_of(...
string string token; size_t pos = -1; // Traverse till stream is valid while (my_stream >> token) { // If ',' is found then tokenize // the string token while ((pos = token.rfind(',')) != std::string::npos) { token.erase(pos, 1); } // Print the tokenize string cout...

使用std::string 时, Chris 的答案可能很好;但是,如果您想使用 std::basic_string,则不能使用 std::getline。这是一个可能的其他实现:template <class CharT> bool tokenizestring(const std::basic_string<CharT> &input, CharT separator, typename std::basic_string<...
