import (
    "fmt"
)

func main() {
    if 7%2 == 0 {
        fmt.Println("7 is even")
    } else {
        fmt.Println("7 is odd")
    }
    //You can have an if statement without an else.
    if 8%4 == 0 {
        fmt.Println("8 is divisible by 4")
    }
    //A statement can precede conditionals; any variables declared in this statement are available in all branches.
    if num := 9; num < 0 {
        fmt.Println(num, "is negative")
    } else if num < 10 {
        fmt.Println(num, "has 1 digit")
    } else {
