What is the likely result of this code if data.txt does not exist? 

fstream file("data.txt", ios::in | ios::out);
if (file.is_open())
    cout << "Opened";
else
    cout << "Failed";

Options

  • A. It prints Opened and creates the file
  • B. It prints Failed because opening generally fails
  • C. It always prints both messages
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. It prints Failed because opening generally fails

Detailed Explanation

Correct Answer: Option B

Explanation:
Opening an existing file with ios::in | ios::out requests reading and writing. If the file does not exist, this combination generally does not create it, so is_open() returns false and the program prints Failed.
