go变量声明和使用

···objective-c

package main

import “fmt”

var x, y int

var (

a int
b bool

)

var c, d int = 1, 2

var e, f = 123, “hello”

func main() {

//这咱不带声明格式的用法，只能出现在函数休内
g, h := 123, "hello"

println(x, y, a, b, c, d, e, f, g, h)

var testString string = "hello world!"

fmt.Println(testString)

var a, b int

a, b = 5, 7

println("a=", a, "b=", b)

a, b = b, a

println("a和b交换后 a=", a, "b=", b)

}
