Go declares that the local variable does not use command line arguments. Main. Go: 4:6: a declared but not used

Declaring global variables that are not used does not report errors
# command-line-arguments
.\main.go:4:6: a declared but not used
package main
import “fmt”
func main(){
var a string=”hhh”;
var b,c int =1,2
fmt.Println(b,c);
}
Correct writing style:
package main
import “fmt”
func main(){
// var a string=”hhh”;
var b,c int =1,2
fmt.Println(b,c);
}
