Which operator inverts the boolean value of its operand? What will be the result of the expression (true && false)?
Understand the Problem
The question is asking for the boolean operator that inverts the value of its operand and the result of a boolean expression involving 'true' and 'false'. The respondent needs knowledge of boolean algebra.
Answer
NOT; false
The operator that inverts the boolean value of its operand is NOT. The result of the expression (true && false) is false.
Answer for screen readers
The operator that inverts the boolean value of its operand is NOT. The result of the expression (true && false) is false.
More Information
The NOT operator inverts the boolean value, turning true to false and vice versa. The && operator requires both operands to be true for the result to be true; otherwise, it returns false.
Tips
A common mistake is confusing the NOT operator with other logical operators such as AND or OR.
