Golang Variables And Inferred Typing

In Golang the var statement declared a list of variables with the type declared last.

var(
  name string
  age int
  location string
)

Or even

var(
  name, location string
  age int
)

Variables can also be declared one by one

var name string
var age int
var location string

A var declaration can include initializers, one per variable

var(
  name string = "Mayra"
  age int = 27
  location string = "MTY"
)

If an initializer is present the type can be omitted, the variable will take the type of the initializer (inferred typing)

var(
  name = "Mayra"
  age = 27
  location = "MTY"
)

You can also initialize variables on the same line:

var(
  name, location, age = "Mayra", 27, "MTY"
)

Inside a function, the := short assignment statement can be used in place of var declaration with implicit type

func main(){
  name, location := "Mayra", "MTY"
  age := 32
  fmt.Printf("%s (%d) of %s", name, age, location)
