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