變數是什麼
建立變數
改變變數
小駝峰命名法
如何寫 comment
如何印出包含文字和變數的內容
概念：
用你的話解釋 var 和 let 的功能和差別。
定義變數的時候，冒號後面會放什麼資訊？
用 Swift 慣用的命名法來重新命名這幾個字串「family_name」、「happy dance」、「GAME OF THRONE」。
family_name → familyName
happy dance → happyDance
GAME OF THRONE → gameOfThrone
let name = "Jane"
var phoneNumber = "0912345678"
print("\(name) 的電話號碼是\( phoneNumber)")
phoneNumber = "0988777666"
print("\(name) 改電話號碼了，新的號碼是 \(phoneNumber)")
// 2. 定義三個變數，分別代表年、月、日。假設今天是 2022 年 8 月 5 日，印出一句話描述今天日期，再修改變數，印出一句話描述明天日期。
let year=2022
let month=8
var day=11
print("今天是\(year)年\(month)月\(day)日")
