What happens if the fopen function fails to open the specified file?
- The program crashes
- It returns a NULL pointer
- It displays an error message on the console
- It opens a default file
The correct option is b. It returns a NULL pointer. When the fopen() function fails to open the specified file, it returns a NULL pointer, indicating that the file opening was unsuccessful. Programmers can then check for this NULL value to handle errors gracefully.
