___ mainPut the learning moves in the order that makes the concept easiest to apply.
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)
}
