GO语言练习：值与引用

1、代码

2、运行

---

 package main

 import "fmt"

 func testValue(){
     fmt.Println("for value")
     var a = [3]int {1, 2, 3}
     var b = a
     b[1]++
     fmt.Println("a = ",a, "\nb = ", b)
 }

 func testReference() {
     fmt.Println("for reference")
     var a = [3]int {1, 2, 3}
     var b = &a
     b[1]++
     fmt.Println("a = ",a, "\nb = ", *b)
 }

 func main() {
     testValue()
     testReference()
 }

2、运行

$ go run valueAndRreference.go
for value
a =  [1 2 3]
b =  [1 3 3]
for reference
a =  [1 3 3]
b =  [1 3 3]
