        } else {
            fmt.Println("7 is odd")
        }

        //if statement without an else.

        if 8%4 == 0 {
            fmt.Println("8 is divisible by 4")
        }
        
        // if statement with declaration of variable
        // variable will be persis in the current and all subsequent branches.
