What type of programming error is illustrated by a program that asks 'What is 2 x 3?' and produces an incorrect result due to flawed logic?

• A. Syntax error
• B. Runtime error
• C. Logic error
• D. Semantic error

Answer: (C)

The main idea is that errors in the program’s reasoning or algorithm produce a wrong result even though the code runs. Here, the program asks for 2 x 3 but returns an incorrect answer because the steps it uses to compute the result are flawed. There are no syntax mistakes that would stop the program from running, and it doesn’t crash during execution, so it isn’t a runtime error. The issue is with how the calculation is performed—the logic behind the result is incorrect—so this is a logic error. If you fixed the computation to correctly implement multiplication (so 2 x 3 yields 6), the program would produce the right output.
