You could also use Karma (part of the Spirit 2 library) for that job.
See the included example.

HTH,

#include <boost/assign/std/vector.hpp>  // for 'operator+=()'

using namespace boost::assign;          // bring 'operator+=()' into scope

int main()

    std::vector<int> v;
    v += 23, 1, 4, 742, 234, 0;

    std::string generated;
    bool success = karma::generate(std::back_inserter(generated),

    return EXIT_SUCCESS;
