HARDObject-Oriented Programming

File I/O question — quiz.txt is pre-loaded for you during grading.

Declare class QuizItem with private Question, Answer and Points. Write NEW, GetQuestion() and CheckAnswer(Guess) which returns TRUE when Guess matches Answer exactly.

The file quiz.txt stores three items as repeating triples of lines: question, answer, points. Load the three objects, then read a choice 1–3 and a guess. Output the chosen question, then Correct or Wrong.

Input: Choice (1, 2 or 3), then a guess. Output: The question text, then Correct or Wrong.

        Paris
