No the program is just

#include <boost/accumulators/framework/accumulator_set.hpp>
#include <boost/accumulators/statistics/count.hpp>

int main() {
boost::accumulators::accumulator_set<int,
boost::accumulators::features<boost::accumulators::tag::count> > acc;
std::size_t c= boost::accumulators::count(acc);
}
