変数定義の仕方

Bo☆Be☆Ro☆Ku
n番煎じ

sample.go
// 宣言、代入
var s string
s = "string"

// 型宣言と代入を一緒に
var s string = "string"

// 型省略
var s = "string"

// var省略
s := "string"

// 同じ型で複数宣言
var s1, s2 string
s1, s2 = "s1", "s2"
// 同じ値を代入はNG
s1, s2 = "s"

// 同じ型で複数代入
s1, s2 := "s1", "s2"

// 別々の型複数宣言
var (
  i int
  s string
)

// 別々の型複数代入
var (
  i = 1
  s = "s"
)
