C++ preg_split_delim_capture() 구현

aaa1bbb2ccc

#include <iostream>
#include <vector>
#include <regex>
using namespace std;

int main() {
    string s("aaa1bbb2ccc");
    regex r("([0-9])");
    vector<std::string> tokens(sregex_token_iterator(s.begin(), s.end(), r, {-1, 0}), sregex_token_iterator());
    for (string t: tokens) cout << t << ", "; // aaa, 1, bbb, 2, ccc, 
}

123aaa

#include <iostream>
#include <vector>
#include <regex>
using namespace std;

int main() {
    string s("123aaa");
    regex r("([0-9])");
    vector<std::string> tokens(sregex_token_iterator(s.begin(), s.end(), r, {-1, 0}), sregex_token_iterator());
    for (string t: tokens) cout << t << ", "; // , 1, , 2, , 3, aaa, 
}
