Example of UUID generation in c++

Question

Hi everyone,

I'm quite a newbie in c++ and I want to generate just random UUID's, as it is just important for instances in my program to have unique identifiers. I looked into Boost UUID, but I can't manage to generate the UUID because I don't understand which class and method to use.

In Java it is as simple as java.util.UUID.randomUUID().

So I would appreciate if someone could give me any example of how to achieve this.

Thank you!

A basic example:

#include <boost/uuid/uuid.hpp>            // uuid class
#include <boost/uuid/uuid_generators.hpp> // generators
#include <boost/uuid/uuid_io.hpp>         // streaming operators etc.

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

Example output:
