在c ++中生成唯一ID

#include<iostream>
#include<random>
#include<chrono>
#include<string>

std::string generate_unique_id() {
    static std::mt19937_64 eng(std::chrono::system_clock::now().time_since_epoch().count());
    static std::uniform_int_distribution<uint64_t> dist;

    uint64_t unique_id = dist(eng);
    return std::to_string(unique_id);
}

int main() {
    std::string unique_id = generate_unique_id();
    std::cout << "Generated unique ID: "<< unique_id<< std::endl;
    return 0;
}
