如何平方我数组中的所有数字？

Question

package mainimport (    "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)

Answer 1

你可能想要这样的东西：

package main

import (

  "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)

}
