Drill 18: Why this way — Variables and control flow

package main

func main() {
    var minutes int
    var published bool
    fmt.Println(minutes, published)

    minutes = 12
    published = true
    title := "Variables and control flow"

    if published && minutes >= maxLessons {
        fmt.Println(title, "is long")
    } else {
        fmt.Println(title, "is short")
    }

    case 12:
        fmt.Println("steady")
    default:
        fmt.Println("other")
    }

    for i := 1; i <= 3; i++ {
        fmt.Println("lesson", i)
