Example of UUID generation using Boost in C++

Question

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 gene

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 

#include             // uuid class
#include  // generators
#include          // 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;
}
