Golang 学习笔记-- 快速上手/重点整理 - 2 - var, const

print

import ("fmt")fmt.Println('hello')

宣告 变数

var variablename type = valuevar a int = 1var a = 1#仅用于function内variablename := value

多变数

  var a, b, c, d int = 1, 2, 3, 4  var a, b = 1, "Hi"  a, b := 3, "Hi"    var (     w = 4     x string     y int = 1     z string = "good"  )

变数类型

const

宣告方法与 variable 类似

const CONSTNAME type = valueconst a = 'hi'

多个 const 宣告

const (  w int = 1  x = 2  y = "Hi")
