Program Correctness

Program Correctness. Program Verification. An object is a finite state machine: Its attribute values are its state. Its methods optionally: Transition it from 1 state to another; Produce a return value. We deal with static methods: Functions. The discussion can be extended to objects.

4.5 Program Correctness

4.5 Program Correctness. Definition 1: A program, or program segment, S is said to be partially correct with respect to the initial assertion p and the final assertion q if whenever p is true for the input values of S and S terminates, then q is true for the output values of S.
