What does "correctness" mean in programming?
correctness is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The degree to which software behaves according to its specification. A correct program does what it is supposed to do for all valid inputs. Verified through tests, proofs, and formal methods.
