Step 1
State what is meant by a syntax error and a logic error.
Answer
A syntax error refers to a mistake in the code that violates the grammatical rules of the programming language, making it impossible for the code to compile or run successfully.
A logic error occurs when the program runs without crashing, but produces incorrect results due to flaws in the algorithm or reasoning behind the code.
Step 2
Identify two logic errors in the pseudocode algorithm.
Answer
-
Error 1 line number: 03 Corrected line:
scores[scoreCount] = total + scores[scoreCount]This line should have a correct initialization and accumulation oftotalastotal = total + scores[scoreCount]. -
Error 2 line number: 02 Corrected line:
for scoreCount = 0 to scores.length - 1The for loop should start from 0 since this is a 0-indexed array.
