将Javascript UUID函数转换为C++

#include <iostream>
#include <random>
#include <sstream>
#include <iomanip>

std::string generateUUID() {
    std::random_device rd;
    std::mt19937 gen(rd());
    std::uniform_int_distribution<> dis(0, 15);

    std::stringstream ss;
    for (int i = 0; i < 32; ++i) {
        int rand_num = dis(gen);
        if (i == 8 || i == 12 || i == 16 || i == 20) {
            ss << "-";
        }
        ss << std::hex << rand_num;
    }

    return ss.str();
}

int main() {
    std::string uuid = generateUUID();
    std::cout << "Generated UUID: " << uuid << std::endl;

    return 0;
}
