How to split a string with multiple separators in C++

Answer 1

#include <iostream>
#include <string>
#include <regex>
#include <vector>

std::vector<std::string> splitByDelimiters(const std::string& input) {
    std::regex re("[,;|\\-_]+"); // Delimiters: comma, semicolon, pipe, dash, underscore
    std::sregex_token_iterator iter(input.begin(), input.end(), re, -1);
    std::sregex_token_iterator end;
    
    return {iter, end};
}

int main() {
    std::string input = "abc,defg;hijk|lmnop-qrst_uvwxyz";
    std::vector<std::string> result = splitByDelimiters(input);

    for (const std::string& word : result) {
        std::cout << word << std::endl;
    }
}



/*
run:

abc
defg
hijk
lmnop
qrst
uvwxyz
