Extracts the current std::match_results from a regex_iterator.
[edit] Return value
1) Returns a reference to the current std::match_results .
2) Returns a pointer to the current std::match_results .
[edit] Example
Run this code
#include <iostream> #include <regex> #include <string> int main() { std::string hay{"1.1a2b3cjk34"}; std::regex needle("[1234]"); using Ri = std::regex_iterator <std::string::iterator>; for (Ri it{hay.begin(), hay.end(), needle}, last{}; it != last; ++it) std::cout << it->str(); std::cout << '\n'; }
Output:
112334
