Bowling Game: State Machine: Unique_Ptr: Step 32

Adding the missing code to AddSpare results in this:

    void AddSpare(int pins)
    {
        switch (bonusRolls)
        {
        case Bonus::NoBonusRolls : score += pins;   bonusRolls = Bonus::OneBonusRoll; ++frame; break;
        case Bonus::OneBonusRoll : score += pins*2; bonusRolls = Bonus::OneBonusRoll; ++frame; break;
        case Bonus::TwoBonusRolls: score += pins*2; bonusRolls = Bonus::OneBonusRoll; ++frame; break;
        }
    }

Now, I could refactor out the ++frame, but I’m still uncertain if I need a case for the Bonus::TwoStrikesBonusRolls case.

So I’ll write a quick test for 3 strikes in a row, a spare and a bonus, but it just passes. So we don’t have to handle that last case.

Let’s refactor both the AddSpare and AddStrike methods to move the ++frame outside the switch, setting us up to reuse the private AddRoll method.
