swift向方法传数组参数的语法

Posted 2020-07-11 chenyangsocool

总是记不住向方法中传数组参数的语法，所以记录一下。

func calculateStatistics(scores:[Int]) -> (min:Int,max:Int,sum:Int) {
    var min = scores[0]
    var max = scores[0]
    var sum = 0
    
    for score in scores {
        if score>max {
            max=score
        }
        else if score<min{
            min=score
        }
        sum += score
    }
    return (min,max,sum)
}
let a=calculateStatistics([5,3,100,3,9])
print(a.min)
print(a.sum)
print(a.0)

最主要的是这句：func calculateStatistics(scores:[Int]) -> (min:Int,max:Int,sum:Int) {}
