boost::minstd_rand usage

[Alex Vinokur]

Hi,

I need to generate randomal integers (0 - 2^31) with
boost::minstd_rand.

Any sample of minstd_rand usage?

Thanks in advance,

Thanks.
But I would like to see any piece of code with use of minstd_rand.

#include <iostream>
#include <iterator>
#include <vector>
#include <set>
#include <boost/random.hpp>
#include <boost/config.hpp>

int main()
{
const size_t totalGeneratedNumbers = 0x200000;

std::vector<unsigned int> v;

boost::minstd_rand m;

mr.seed (0x12345678);

std::generate_n( std::back_inserter(v), totalGeneratedNumbers, m);

const std::set<unsigned int> s (v.begin(), v.end());

if (s.size() == v.size())
{
std::cout << "No number repetitions" << endl;
}
else
{
std::cout << "There are number repetitions" << endl;
}


return 0;
}
