There are many ways to assign a variable in Go. Here below are some of those which I have encountered till date.
Syntax: var i int
package main
import "fmt"
func main() {
var i int
fmt.Println(i)
}
The var statement can be at either package or function level and it declares a list of variables the type is last.
If an initializer is present, the type can be omitted and the variable will assume the type of the initializer. Example :
package main
import "fmt"
var i, j int = 1, 2
func main() {
var c, python, java = true, false, "no!"
fmt.Println(i, j, c, python, java)
}
Interesting syntax :=
Inside a function, the := short assignment statement can be used in place of a var declaration with implicit type.
Example:
package main
import "fmt"
func main() {
var k int = 3
//:= is short assignment can be used in place of var declaration with implicit type.
l := 3
fmt.Println(k, l)
}
Output :
k is 3
l is 3
