What does the term 'iff' refer to in programming logic?

1. A logical equivalence between two statements

2. A conditional statement with two outcomes

3. A multi-conditional statement

4. A statement that guarantees one outcome

The correct answer is: A conditional statement with two outcomes

The term 'iff' is a logical abbreviation that stands for "if and only if." In programming logic, this indicates a logical equivalence between two statements, meaning that both statements are true together or false together. It establishes a strong connection between the two conditions, showing that they imply each other. The correct response highlights that 'iff' indicates a specific type of conditional relationship that asserts two outcomes: one condition is true if and only if the other condition is true. This necessity effectively captures the essence of logical equivalence. The other choices reflect different logical concepts, with some being related to conditional logic but not capturing the full meaning of 'iff'. For instance, a conditional statement with two outcomes describes a basic if-then scenario rather than the bidirectional nature of 'iff'. Multi-conditional statements expand on multiple conditions but do not specifically address the equivalence that 'iff' stands for. Lastly, a statement that guarantees one outcome does not adequately reflect the mutual truth condition that 'iff' establishes. Thus, the focus on logical equivalence makes the answer about logical equivalence the most accurate understanding of 'iff' in programming logic.
