First of all, it seems that you've got a using namespace std; somewhere in your code. Don't do that. (No, really).

Here's a function that should meet your needs.

static std::string Read(std::istream &stream, std::string::size_type count)
{
 std::string out;
 out.reserve(count);
 std::copy_n(std::istreambuf_iterator(stream), count, std::back_inserter(out));
 return out;
}
