5. If Statements and Choices

5.1 The If, Elseif, and Else rules

Programs can make smart choices. It will check a rule. If the rule is True, it does the action. If not, it can check another rule using Elseif or do a default action using Else.

Number age = 10.
If (age > 18) {
    Displaynl("You are an adult.").
}
Elseif (age == 18) {
    Displaynl("You just became an adult!").
}
Else {
    Displaynl("You are a kid.").
}

5.2 Using Switch for Many Choices

When you have lots of exact choices to pick from, a Switch is cleaner than writing many If rules.

Number luck = 2.
Switch(luck) {
    Case(1) {
        Displaynl("Gold Coin!").
    }
    Case(2) {
        Displaynl("Silver Coin!").
    }
    Default {
        Displaynl("No Coin!").
    }
}
