In boolean logic, which operator negates a value?

In boolean logic, which operator negates a value?

• A. AND
• B. OR
• C. NOT
• D. XOR

Answer: (C)

Negation is the operation in boolean logic that inverts a value. It flips true to false and false to true, applying to a single statement to yield its opposite. For example, NOT true is false, and NOT false is true. The other basic operators combine two values to produce a result: AND requires both inputs to be true to yield true; OR yields true if at least one input is true; XOR yields true only when exactly one input is true. Because negation changes the value itself rather than combining two values, it is the operator that negates a value.
