Which of the following best describes a logic error?

A logic error refers to a flaw in the program's design or reasoning that leads to incorrect results despite the program executing without crashing. This type of error means that the code runs, but it doesn't do what the programmer intended it to do. In this context, option B accurately describes a logic error, as it focuses on the incorrect result produced during program execution.

For instance, a program may perform calculations and run smoothly, but if the formula used is wrong—like adding when it should be subtracting—a logic error occurs. The program does not prevent compilation, so it's not related to option A. It also does not involve syntax issues, which option C addresses, nor is it specifically tied to input operations, as indicated by option D. Logic errors primarily hinge on the flawed logic or implementation in the coding process rather than structural or syntactical mistakes.
