Question

How do I read a binary file into a bitset or vector? The binary file will vary in length. Is there a better container for this? I am ne

You didn't give too much context of what you're trying to do in your question. But here's one quick & dirty way to do it:

#include 
#include 
#include 
#include 
using namespace std;

const char *filename = "foo.bar";
int main()
{
  vector v;
  ifstream binary_file(filename, ios::binary);

  assert(binary_file);
  copy(istream_iterator(binary_file),
       istream_iterator(),
       back_insert_iterator< vector >(v));
}

Reading the zero-byte '\0' character into the vector will be false. Any other bytes read in will be treated as true.
