如何平方我数组中的所有数字？

Question

package main

import (

    "fmt"

)

func main() {

    var square int

    box := [4]int{1, -2, 3, 4}

    square = box * *box

    fmt.Println("The square of the first box is", square)

}

谁能告诉我正确的平方方法？问题是无效直接的 square(type[4]int)

你可能想要这样的东西：package mainimport (  "fmt")func main() {  box := []int{1, -2, 3, 4}  square := make([]int, len(box))  for i, v := range box {    square[i] = v*v  }  fmt.Println("The square of the first box is ", square)}
