Go by Example: Variables

In Go, variables are explicitly declared and used by the compiler to e.g. check type-correctness of function calls.
	package main
	import "fmt"
	func main() {
`var` declares 1 or more variables.	var a string = "initial" fmt.Println(a)
You can declare multiple variables at once.	var b, c int = 1, 2 fmt.Println(b, c)
Go will infer the type of initialized variables.	var d = true fmt.Println(d)
Variables declared without a corresponding initialization are zero-valued. For example, the zero value for an `int` is `0`.	var e int fmt.Println(e)
The `:=` syntax is shorthand for declaring and initializing a variable, e.g. for `var f string = "short"` in this case.	f := "short" fmt.Println(f) }

$ go run variables.go
initial
1 2
true
0
short
