defining (one/two) dimensional array of boost::dynamic_bitset

Question

Is there a way to have an array of dynamic_bitset in boost? I would like to be able to have both 1-D and 2-D arrays -- Thanks!

Answer 1

If you can use a std::vector that would probably be better and yes you can do both, here is an example (see it live):

#include <iostream>
#include <vector>
#include <boost/dynamic_bitset.hpp>

int main()
{
    std::vector<boost::dynamic_bitset<> > v(10, boost::dynamic_bitset<>(3));

    std::cout << v[0] << std::endl ;

    v[0][2] = 1 ;

    std::cout << v[0] << std::endl ;

    std::vector< std::vector<boost::dynamic_bitset<> > > vv(3, std::vector<boost::dynamic_bitset<> >( 3, boost::dynamic_bitset<>(3)) );

    std::cout << vv[0][0] << std::endl ;

    vv[0][0][1] = 1 ;

    std::cout << vv[0][0] << std::endl ;
}
