Tutorial Difficulty Level Go variables of different types can be declared in one go using type inference.
package main
import "fmt"
func main() {
var a, b, c = 3, 4, "foo"
fmt.Println(a)
fmt.Println(b)
fmt.Println(c)
fmt.Printf("a is of type %T\n", a)
fmt.Printf("b is of type %T\n", b)
fmt.Printf("c is of type %T\n", c)
}
When the above code is compiled and executed, it produces the following result:
3 4 foo a is of type int b is of type int c is of type string
