简单

在上一课中，你计算了小费金额和加上小费后的总金额。现在，添加最后一步计算，确定分摊账单时每个人需要支付多少。

使用你已经计算出的 totalWithTip 和 numberOfPeople，用总金额除以人数，计算每个人应支付的金额。

记得在进行除法之前，将 numberOfPeople 从 Int 转换为 Double。

更新输出，使其按以下确切格式打印：

Welcome to the Bill Split Calculator!
Bill: [billTotal]
Tip: [tipPercentage]%
People: [numberOfPeople]
Tip amount: [tipAmount]
Total with tip: [totalWithTip]
Each person pays: [amountPerPerson]

例如，如果输入是 100.0、20 和 4，输出应为：

Welcome to the Bill Split Calculator!
Bill: 100.0
Tip: 20%
People: 4
Tip amount: 20.0
Total with tip: 120.0
Each person pays: 30.0

亲手试试

print("Welcome to the Bill Split Calculator!")

if let billInput = readLine(), let billTotal = Double(billInput) {
    if let tipInput = readLine(), let tipPercentage = Int(tipInput) {
        if let peopleInput = readLine(), let numberOfPeople = Int(peopleInput) {
            let tipAmount = billTotal * Double(tipPercentage) / 100
            let totalWithTip = billTotal + tipAmount
            
            print("Bill: \(billTotal)")
            print("Tip: \(tipPercentage)%")
            print("People: \(numberOfPeople)")
            print("Tip amount: \(tipAmount)")
            print("Total with tip: \(totalWithTip)")
        }
    }
}
