拆分字符串并添加到char数组吗？

#include <iostream>
#include <sstream>
#include <string>

void splitAndAddToCharArray(const std::string& str, char* charArray, char delimiter) {
    std::stringstream ss(str);
    std::string token;
    int index = 0;

    while (std::getline(ss, token, delimiter)) {
        const char* cstr = token.c_str();
        for (int i = 0; i < token.length(); i++) {
            charArray[index++] = cstr[i];
        }
    }
}

int main() {
    std::string str = "Hello,World!";
    char charArray[20];

    splitAndAddToCharArray(str, charArray, ',');

    for (int i = 0; i < str.length(); i++) {
        std::cout << charArray[i];
    }

    return 0;
}
