C#.NET — Which of the following is correct about the Bitwise XOR operator (^) ?

Introduction / Context:
This question deals with the XOR (exclusive OR) bitwise operator in C#.

Given Data / Assumptions:

• Operator: ^ (bitwise XOR).
• Rule: 0 ^ 1 = 1, 1 ^ 1 = 0.

Concept / Approach:
XOR flips bits where the other operand has 1. This property allows toggling (inverting) selected bits.

Step-by-Step Solution:

Verification / Alternative check:
For bit toggle: value ^ 0xFF inverts all bits of value.

Why Other Options Are Wrong:
XOR does not always set ON or OFF; it toggles depending on mask. It is not used for bit testing directly.

Common Pitfalls:
Confusing XOR with OR. XOR is for toggling, not just turning bits ON.

Final Answer:
The ^ operator can be used to invert a bit.
