Tags : golang square elements array

Problem :

You need to calculate the square values of the elements in an array or slice.

Solution :

Make a new array and use for loop to square all the elements.

For example :

 package main

 import (
  "fmt"
 )

 func main() {
  arr := []int{1, 2, 3, 4, -5, 6}

  squareArray := make([]int, len(arr))

  for k, v := range arr {
 squareArray[k] = v * v
  }

  fmt.Println("The square of all the elements in the array box is ", squareArray)
 }

Output :

The square of all the elements in the array box is [1 4 9 16 25 36]
