Go Multiple Variable Declaration
Go Multiple Variable Declaration
In Go, it is possible to declare multiple variables in the same line.
Example
This example shows how to declare multiple variables in 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)
}

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 in 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)
}
