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.
I would appreciate if someone could give me any example of how to achieve this.
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:
7feb24af-fc38-44de-bc38-04defc3804de
The answer of Georg Fritzsche is ok but maybe a bit misleading. You should reuse the generator if you need more than one uuid.
Maybe it's clearer this way:
#include <iostream>
#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::random_generator generator;
boost::uuids::uuid uuid1 = generator();
std::cout << uuid1 << std::endl;
boost::uuids::uuid uuid2 = generator();
std::cout << uuid2 << std::endl;
return 0;
}
