Solution

All of the mentioned statements are true.

  1. When you open a file for reading, if the file does not exist, an error occurs. This is because the system cannot find the specified file to read from.

  2. When you open a file for writing, if the file does not exist, a new file is created. This is because the system needs a file to write to, so if it cannot find an existing file, it creates a new one.

  3. When you open a file for writing, if the file exists, the existing file is overwritten with the new file. This is because the system assumes that you want to replace the existing file with the new information you are writing.

So, all of the mentioned statements are true.
