This seems to work for me:

using namespace std;
int main() 
{ 
  fstream inout("C:\\Users\\turdfurguson\\Turds\testfile.txt", ios::in | ios::out | ios::binary);
  if (inout.good())
    cout << "OK!" << endl;
}

Provided you have a "C:\Users\turdfurgson\Turds\testfile.txt" file that is readable and writable.

The code you've provided looks fine.

You may have supplied the wrong path or something like that.

You could also try attempting to open that file in read only mode and see if that is ok:

std::ifstream in("path", std::ios::binary);

if (!in) {
   // fail
}
