类在Swift中接收数组

var numbers: [Int] = [1, 2, 3, 4, 5]

var numbers = [1, 2, 3, 4, 5]

class ArrayCalculator {
    func sum(numbers: [Int]) -> Int {
        var total = 0
        for number in numbers {
            total += number
        }
        return total
    }
}

let calculator = ArrayCalculator()
let sum = calculator.sum(numbers: [1, 2, 3, 4, 5])
print(sum) // 输出：15

class Student {
    var name: String
    var scores: [Int]
    
    init(name: String, scores: [Int]) {
        self.name = name
        self.scores = scores
    }
    
    func averageScore() -> Double {
        let total = scores.reduce(0, +)
        return Double(total) / Double(scores.count)
    }
}

let student = Student(name: "John", scores: [90, 85, 95, 80, 92])
let average = student.averageScore()
print(average) // 输出：88.4
