Which error type occurs when a program's code is syntactically correct but does not produce the expected outcome?

The situation described pertains to a logic error, which occurs when a program's code adheres to the syntactical rules of the programming language, meaning it compiles and runs without any syntax or compilation errors. However, despite proper syntax, the program does not yield the expected results because the underlying logic or algorithm is flawed. This could be due to incorrect calculations, improper conditions in control statements, or faulty assumptions in the code flow that lead to unintended or incorrect outcomes.

For example, if a program is designed to calculate the average of a set of numbers but mistakenly sums them instead of dividing by the count, it exemplifies a logic error; the program runs successfully but produces an incorrect result. Logic errors require careful analysis and debugging to identify and correct the flawed logic.
