通过实例学Ruby编程
通过实例学Ruby编程
關於本書
2013年12月8日，美国总统奥巴马“要求每一个美国人都要尝试学习编程”，以此拉开计算机科学教育周刊2013年发起的每天学习代码一小时的活动序幕。奥巴马说: “学习这些技能不仅对你的未来十分重要，它对国家的未来也意义重大。” 可见，编程是这个信息时代一个重要的技能。
一个典型的教授如何编程的书将通过编程概念，语法和用简单例子做示范等方式来教学。我以前看过几十本这样的编程语言或工具书，而且在大学任教时也是用这种方式教学。我认为这并不是一种有效的方法，因为它更像是一个老师对学生的知识倾倒。我相信更好的办法是，让学生们通过编程练习循序渐进地学习，并指导他们解决有趣和实用的计算机程序，包括：
• 求最大公约数
• 个人所得税计算
• 随机产生六合彩号码
• 狼、羊、白菜和农夫过河谜题
每个练习(共43个)都有针对性地引进新的编程概念并适当地巩固先前知识。本书强调实用性并着重培养读者的编程思维能力。书的最后一章介绍了利用编程来做自动化测试，这是在美国评为最幸福职业 “软件测试工程师”的必备技能。
我把我的编程教学思想付诸实践，本书也是在教我的13岁的女儿Courtney学习编程时所做的总结。
Ruby是一种流行的编程语言，它被广泛用于Web应用程序和软件测试。 由于Ruby的简单，优雅和简洁的语法，它被认为是最佳的初学编程语言之一。
