[Boost-users] How to use bind with explicit constructor conversion?

18 Nov 2006


      This doesn't compile.
How best to accomplish this using generic STL or Boost algorithms/adapters?

int main() {
  vector<MyInt> v;

  // Do this:
  //   for (int i=0; i!=30; ++i) v.push_back(MyInt(rand()));
  generate_n(back_inserter(v), 30, bind(MyInt, bind(rand)));

  // Now print v.
  transform(v.begin(), v.end(), ostream_iterator<int>(cout, "\n"),
      mem_fn(&MyInt::value));

  return 0;
} // main
