Variables - Golang

11 Jul, 2021

In Go, variables are explicitly declared and used by the compiler to e.g. check type-correctness of function calls.

• var declares 1 or more variables.
• You can declare multiple variables at once.
• Go will infer the type of initialized variables.
• Variables declared without a corresponding initialization are zero-valued. For example, the zero value for an int is 0.
• The := syntax is shorthand for declaring and initializing a variable, e.g. for var f string = "apple" in this case.

package main
import "fmt"

func main() {

    var a = "initial"
    fmt.Println(a)

    var b, c int = 1, 2
    fmt.Println(b, c)


    var d = true
    fmt.Println(d)

    var e int
    fmt.Println(e)
