T F Several file access flags may be joined by using the | operator.

Provide an explanation and example. Answer: Yes, several file access flags can be joined by using the | operator. The | operator is a bitwise OR operator in programming languages like C and Python, and can be used to combine multiple file access flags together. For instance, in Python, to open a file in both read and write mode, we can either use the 'r+' flag or combine the read-only ('r') and write-only ('w') flags using the | operator, as demonstrated in the following code: ```python import os # Using the 'r+' flag file1 = open("example.txt", "r+") # Using the | operator to combine 'r' and 'w' flags file2 = open("example.txt", os.O_RDWR | os.O_TRUNC) ``` In this example, both 'file1' and 'file2' are opened in read and write mode, with the | operator used to combine the read-only and write-only flags in the second example.
