问题描述

我有 2 个像这样 Int 类型的数组

I have 2 Array of type Int like this

let arrayFirst = [1,2,7,9]
let arraySecond = [4,5,17,20]

我想把每个数组的元素相加，比如arrayFirst[0] + arraySecond[0]、arrayFirst[1] + arraySecond[1]等等，然后赋值给另一个数组，这样数组的结果就会就像

I want to add the elements of each array, like arrayFirst[0] + arraySecond[0], arrayFirst[1] + arraySecond[1] an so on and assign it to another array, so the result of the array would be like

[5, 7, 24, 29]

[5, 7, 24, 29]

使用 swift3

推荐答案

你可以像这样添加两个数组

You can add both the arrays like this

let arrayFirst = [1,2,7,9]
let arraySecond = [4,5,17,20]

let result = zip(arrayFirst, arraySecond).map(+)
print(result)
