📚 Year 13 CAIE Computer Science: Case Study Practical Drills | Year 13 CAIE 计算机：案例分析实战演练

In CAIE A-Level Computer Science (9618), Paper 4 requires you to apply computational thinking and programming skills to a given case study scenario. This article provides a systematic, step-by-step practical drill using a library book management system as our example, so you can master the approach and score high marks.

在 CAIE A-Level 计算机科学（9618）考试中，Paper 4 要求你将计算思维和编程技能应用于一个给定的案例场景。本文以图书馆图书管理系统为例，提供系统化的逐步实战演练，帮助你掌握解题方法并取得高分。

1. Understanding the Problem Statement | 理解问题陈述

Begin by carefully reading the problem brief. In our scenario, we need to develop a program that manages library books: adding new books, issuing books to members, returning books, and generating reports. Note any constraints — for example, the maximum number of books is 1000, and data must be stored in a text file.

首先仔细阅读问题描述。在我们的场景中，需要开发一个管理图书馆图书的程序，包括添加新书、借出给会员、归还图书和生成报告。注意所有约束条件，例如最大书本数量为 1000，并且数据必须存储在文本文件中。

Highlight the inputs (book details, member ID), outputs (confirmation messages, reports), and any specified file format (e.g., CSV). Identifying these early prevents misinterpretation later.

标出输入（图书详情、会员 ID）、输出（确认信息、报告）以及指定的文件格式（如 CSV）。尽早识别这些可以避免后续的误解。
