Bowling Game: State Machine: Unique_Ptr: Step 27

Adding the third if clause passes the last test:

        void AddStrike()
        {
            if (bonusRolls == Bonus::OneBonusRoll)
            {
                score += 20;
                bonusRolls = Bonus::TwoBonusRolls;
                ++frame;
                return;
            }
            if (bonusRolls == Bonus::TwoBonusRolls)
            {
                score += 20;
                bonusRolls = Bonus::TwoStrikesBonusRolls;
                ++frame;
                return;
            }
            if (bonusRolls == Bonus::TwoStrikesBonusRolls)
            {
                score += 30;
                bonusRolls = Bonus::TwoStrikesBonusRolls;
                ++frame;
                return;
            }

            score += 10;
            bonusRolls = Bonus::TwoBonusRolls;
            ++frame;
        }

There’s so much commonality now that I can’t take it anymore. Let’s refactor all these ifs to switch statements, in both the AddStrike and AddRoll methods.

Do that refactoring, and then click next.
