Go Multiple Variable Declaration
Go Multiple Variable Declaration
In Go, it is possible to declare multiple variables on the same line.
Example
This example shows how to declare multiple variables on the same line:
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)
}
Try it Yourself »
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)
}
Try it Yourself »
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)
}
Try it Yourself »
import "fmt"
func main() {
var (
a int
b int = 1
c string = "hello"
)
fmt.Println(a)
fmt.Println(b)
fmt.Println(c)
}
