c++中如何生成uuid_c++生成UUID方法

#include <iostream>
#include <boost/uuid/uuid.hpp>
#include <boost/uuid/uuid_generators.hpp>
#include <boost/uuid/uuid_io.hpp>

int main() {
    boost::uuids::random_generator gen;
    boost::uuids::uuid uuid = gen();
    std::cout << uuid << std::endl;
    return 0;
}

g++ -o uuid_example uuid.cpp -lboost_system -lboost_random

#include <iostream>
#include <objbase.h>

int main() {
    CoInitialize(nullptr);
    GUID guid;
    CoCreateGuid(&guid);
    std::cout << guid_to_string(guid) << std::endl;
    CoUninitialize();
    return 0;
}
