Copy an array by value and reference into another array

You can create copy of an array, by assigning an array to a new variable either by value or reference.

Example

package main

import "fmt"

func main() {

	strArray1 := [3]string{"Japan", "Australia", "Germany"}
	strArray2 := strArray1  // data is passed by value
        strArray3 := &strArray1 // data is passed by refrence

	fmt.Printf("strArray1: %v\n", strArray1)
        fmt.Printf("strArray2: %v\n", strArray2)	

        strArray1[0] = "Canada"
  
	fmt.Printf("strArray1: %v\n", strArray1)
	fmt.Printf("strArray2: %v\n", strArray2)	
	fmt.Printf("*strArray3: %v\n", *strArray3)	
}

Output

strArray1: [Japan Australia Germany]
strArray2: [Japan Australia Germany]
strArray1: [Canada Australia Germany]
strArray2: [Japan Australia Germany]
*strArray3: [Canada Australia Germany]
