Go Multiple Variable Declaration

In Go, it is possible to declare multiple variables on the same line.

Example

package main
import ("fmt")
func main() {
  var a, b, c, d int = 1, 3, 5, 7
  fmt.Println(a)
  fmt.Println(b)
  fmt.Println(c)
  fmt.Println(d)
}

Note

If you use the type keyword, it is only possible to declare one type of variable per line.

If the type keyword is not specified, you can declare different types of variables on the same line:

Example

package main
import ("fmt")
func main() {
  var a, b = 6, "Hello"
  c, d := 7, "World!"
  fmt.Println(a)
  fmt.Println(b)
  fmt.Println(c)
  fmt.Println(d)
}

Go Variable Declaration in a Block

Multiple variable declarations can also be grouped together into a block for greater readability:

Example

package main
import ("fmt")
func main() {
  var ( a int
  b int = 1
  c string = "hello" )
  fmt.Println(a)
  fmt.Println(b)
  fmt.Println(c)
}
