Thread: odd I/O compile error

>It is perfectly fine.
How is that? The open member function for ifstream returns void, so you can't use the return value as a test for success. One would need to call the is_open member function to check the status.

Code:

ifstream winfilein("wins.txt"); // ios_base::in is defaulted

if (winfilein.is_open()) {
  winfilein.close();
  // blahblah
}
