实验编号:2四川师大IOS应用开发技术实验报告2017年9月23 日计算机科学学院2015级 班 实验名称：Swift类和子类 姓名 学号： 指导老师：_ 实验成绩:_实验_二_ Swift类和子类一 实验目的及要求 用 Swift语言编写类和子类，掌握类和子类的定义及使用二 实验内容(1) 实现Person类：a) 要求具有firstName, lastName，age，gender等存储属性,fullName计算属性；其中gender是枚举类型（male，female）；b) 具有指定构造函数和便利构造函数；c) 两个Person实例对象可以用=和!=进行比较；d) Person实例可以直接用print输出；e) Person增加run方法(方法里面直接print输出Person XXX is running;(2) 从Person分别派生Teacher类和Student类：a) Teacher类增加属性title，实例可以直接用print输出；b) Student类增加属性stuNo，实例可以直接用print输出；c) Teacher和Student重载run方法(方法里面直接print输出Teacher XXX is running和Student XXX is running)(3) 分别构造多个Person、Teacher和Student对象，并将这些对象存入同一个数组中；(4) 新建一个协议SchoolProtocol，协议包括一个department属性(Enum，自己实现enum的定义)和lendBook方法（随便写点内容，能区隔即可）；(5) 修改Teacher和Student，让这两个类实现该协议；(6) 对数组执行以下要求：a) 分别统计Person、Teacher和Student对象的个数并放入一字典中，统计完后输出字典内容；b) 对数组按以下要求排序并输出：age、fullName、gender+age；c) 对数组进行穷举，调用每个对象的run方法，同时调用满足协议SchoolProtocol对象的lendBook方法； 3、主要仪器设备及药品：iMac（Mac OS、XCode）三 实验结果的分析与评价（该部分如不够填写，请另加附页）（1） 找出从 1-10000 的所有质数，将找出的质数存入可变数组，对数组进行正反排序并输出结果(采用 5 种以上的方法实现)； 代码： func searchPrimNum() - Intvar changeArray = 2,3 /定义可变数组var recordIsPrim = 0 /用于记录判断质数for x in 4.10000 for y in 2.
