Correctness

Correctness. Quality Perceptions. The perception of quality associated with your code is typically bound to: Correctness Efficiency (speed of execution usually) Cost (if it costs more, it must be better right?) Robustness Flexibility Functionality Maintainability Security Usability

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.

Section 8.2 Program Correctness (for imperative programs)

Section 8.2 Program Correctness (for imperative programs) A theory of program correctness needs wffs, axioms, and inference rules. Wffs (called Hoare triples) are of the form { P } S { Q }
