A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.https://en.wikipedia.org › wiki › Logic_errorLogic error – Wikipedia is a problem with a computer’s programming code that is not readily identified when the code is written or compiled.
