arrays - 如何将数组发送到函数(How to send an array into function)

Question

I'm looking to find syntax that how can I send an array to use in a function as input in Go.

(我正在寻找一种语法，该语法如何发送数组以用作Go中的输入。)

You were almost there, here is an example:

(您快到了，这里有个例子：)

package main

import (
    "fmt"
)

func myFunc(arr []int) {
    fmt.Println(arr)
}

func main() {

    var arr = []int{1, 2, 3, 54, 3}
    myFunc(arr)

}

PS As @torek mentioned, to be precise, you are using a slice not an array.

(PS如@torek所述，确切地说，您使用的是切片而不是数组。)

Arrays have constant length and cannot grow, and the function signature for array in my example would be myFunc(arr [5]int) .

(数组具有恒定的长度并且不能增长，在我的示例中，数组的函数签名为myFunc(arr [5]int) 。)
