Question

What defines the circumstances in which a particular operation is valid?

1) Data invariant
2) Precondition
3) Postcondition
4) State

Answer 1

The circumstances that define the validity of a particular operation are the data invariant, precondition, postcondition, and state.

Step-by-step explanation:

The circumstances that define the validity of a particular operation are the data invariant, precondition, postcondition, and state.

1. The data invariant specifies the conditions that remain unchanged throughout the operation.
2. The precondition outlines the conditions that must be true before the operation is applied.
3. The postcondition describes the expected conditions that should hold true after the operation.
4. The state refers to the overall condition or status of the system.
