Swift 结构体

感觉swift的结构体和类有点相似

// 定义结构体
struct Student {
    var name: String
    var age: Int
    var height: Float? // 可选型在构造函数中可以不必初始化
    
    
    init(name: String,age: Int) {
        self.name = name
        self.age = age
    }
    
    init(name: String,age: Int,height:Float) {
        self.name = name
        self.age = age
        self.height = height
    }
}

// 实例化
var stu = Student(name: "gaobo",age: 24)
var stu1 = Student(name: "gaoxiaobo",age: 23,height: 1.8)
