快速/更改循环中的变量名称 [英] swift / changing name of variable in loop

问题描述

我该如何在循环中更改变量的名称?像number1，number2，number3，number4一样?

How could i change name of variable in loop? like number1 , number2, number3, number4 ?

var array = [2,4,6,8]
func ap ( number1: Int , number2: Int , number3: Int , number4: Int ) {
    for (index,_) in array.enumerated() {
    array[index] += **("number\(index)")**
    }
        print(array)
}
ap(number1: 2, number2: 4, number3: 6, number4: 8)

推荐答案

我认为

I think this answer says not possible and to use an array instead.

这里正在使用另一个数组:

Here is using another array:

var array = [2,4,6,8]

func ap ( number1: Int , number2: Int , number3: Int , number4: Int ) {

    let arrayOfParameters = [number1, number2, number3, number4]

    for (index,_) in array.enumerated() {
        array[index] += arrayOfParameters[index]
    }
    print(array)
}
ap(number1: 2, number2: 4, number3: 6, number4: 8)

打印:[4、8、12、16]

prints: [4, 8, 12, 16]
