Correctness (computing)

In computing, correctness refers to whether a program or algorithm behaves as intended, producing the correct output for all valid inputs. It ensures that the software fulfills its specified requirements and functions reliably without errors. Correctness involves verifying that the logic and processes within the program align with its design goals, often through testing or formal proofs. Essentially, a correct program does what it is supposed to do consistently and accurately, which is vital for applications where precision and reliability are critical, like in banking systems or medical devices.
