So, I have mostly finished writing the class to model a game of bowling. I have tested the game code, and it was kind of painful. While writing the code to test the scoring functions, I noticed the code base getting uglier and uglier. After feeling like most of the class was sufficiently debugged, I took a moment to reflect and realized most of the ugliness was in the test code, which made me feel a whole lot better about myself. I think I have way too fragile of an ego to post the debugging code, but since I have nothing to blog about outside the development of this application, I thought I would go ahead and post the scoring code.
Here is the definition of the class modelling a game of bowling:
class CGame : public CObject
{
public:
CGame();
virtual ~CGame();
void ScoreFrame(int nFrame);
void ScoreGame();
void ScoreTenthFrame();
void SetRegularFrame(CFrame* pFrame);
void SetTenthFrame(CTenthFrame* pTenthFrame);
#ifdef _DEBUG
int CalculateScoreByFrame(int nFrame);
void DumpGame();
void MakeFrame(int nFrame, TCHAR chFirst, TCHAR chSecond);
void MakeTenthFrame(TCHAR chFirst, TCHAR chSecond, TCHAR chThird);
void StringToGame(CString sGame);
static bool TestGame();
#endif
static const int NUMREGULARFRAMES = 9;
protected:
int m_nCompletedFrames;
int m_nScoredFrames;
int m_nScoreByFrame[NUMFRAMES];
CFrame* m_pFrames[NUMREGULARFRAMES];
CTenthFrame* m_pTenthFrame;
private:
operator=(const CGame& Game) {};
CGame(const CGame& Game) {};
};
I left the debugging member function declarations in there for an exercise to the read to imagine their ugliness. Believe me, it is probably worse than you imagine. I don't think this class is done, but it most of the way, and it is sufficiently defined to test the major points of functionality. Oh yeah, and
NUMFRAMES is defined in a separate header of global constants. I hope you aren't surprised to learn its value is 10. So lets take a look at the highest level function,
ScoreGame.
void CGame::ScoreGame()
{
for (int i = 0; i < NUMREGULARFRAMES; ++i)
ScoreFrame(i+1);
ScoreTenthFrame();
}
Pretty clean so far. You can't ask for too much more. So how about the function to score a non-tenth frame of bowling with a zero-based index as a parameter.
void CGame::ScoreFrame(int nFrame)
{
ASSERT(nFrame >= 1 && nFrame <= NUMREGULARFRAMES);
if (m_pFrames[nFrame-1]->IsMark())
{
m_nScoreByFrame[nFrame-1] = 10;
}
else
{
m_nScoreByFrame[nFrame-1] = m_pFrames[nFrame-1]->GetCount(1)
+ m_pFrames[nFrame-1]->GetCount(2);
}
if (nFrame >= 2)
{
if (m_pFrames[nFrame-2]->IsSpare())
{
m_nScoreByFrame[nFrame-2] += m_pFrames[nFrame-1]->GetCount(1);
}
else if (m_pFrames[nFrame-2]->IsStrike())
{
if (m_pFrames[nFrame-1]->IsStrike())
{
m_nScoreByFrame[nFrame-2] += 10;
}
else
{
m_nScoreByFrame[nFrame-2] += m_pFrames[nFrame-1]->GetCount(1)
+ m_pFrames[nFrame-1]->GetCount(2);
}
}
}
if (nFrame >= 3)
{
if (m_pFrames[nFrame-3]->IsStrike() && m_pFrames[nFrame-2]->IsStrike())
m_nScoreByFrame[nFrame-3] += m_pFrames[nFrame-1]->GetCount(1);
}
}
Still pretty clean here. Some people might bitch about the nesting level, but that is a style holy war I am not wanting to get involved in. Besides, if you have never worked in statements conditionals nested three deep, you are either some functional programming language sicko or a freshmen undergrad. So how about scoring tenth frame?
void CGame::ScoreTenthFrame()
{
// Check for double in 8th and 9th
if (m_pFrames[7]->IsStrike() && m_pFrames[8]->IsStrike())
{
m_nScoreByFrame[7] += m_pTenthFrame->GetCount(1);
m_nScoreByFrame[8] += m_pTenthFrame->GetCount(1)
+ m_pTenthFrame->GetCount(2);
}
else if (m_pFrames[8]->IsSpare())
{
m_nScoreByFrame[8] += m_pTenthFrame->GetCount(1);
}
m_nScoreByFrame[9] = m_pTenthFrame->GetCount(1)
+ m_pTenthFrame->GetCount(2);
if (m_pTenthFrame->IsMark())
m_nScoreByFrame[9] += m_pTenthFrame->GetCount(3);
}
This code still fairly clean. I suppose some CS professor or software architect type might ding me about the magic numbers, and the CTenthFrame class as opposed to CFinalFrame class with a member indicating the number of the final frame. But in all honesty, I have no intentions of this software being able to handle 15 frame games of bowling a la Randy Quaid in Kinpin. I don't have any inclination to make this score games of candle pin or duck pin, either, so all you Canucks, lay off. :) I guess you could bitch about the magic numbers in the
ScoreFrame function as well. I have to say, I won't lose sleep if my application doesn't score games of bowling in bizarro world that number frames -5 to 5. I just don't think it is necessary to define something like:
const int NINTHFRAME = 8;
when I have it so firmly in grained that array indices are zero-based. As tangent, here is one of my favorite computer sciences quotes that undoubtedly exists to poke fun at programming language style preference holy wars:
Should array indices start at 0 or 1? My compromise of 0.5 was rejected without, I thought, proper consideration. (Stan Kelly-Bootle)
Okay, so I have hinted at underlying ugliness this entire post. It involves the functions for counting pinfall. Let's take a look at the ugliness in increasing order of ugly.
int CShot::GetCount()
{
switch (m_wResult)
{
case MISS:
case FOUL:
return 0;
case STRIKE:
return 10;
case SPARE:
return 10;
default:
int nCount = 0;
for (int i = 0; i < 10; ++i)
{
if ((m_wResult & (1 << i)) != 0)
++nCount;
}
return nCount;
}
}
Not *too* bad, but I can do better: :)
int CFrame::GetCount(int nShot)
{
ASSERT(nShot == 1 || nShot == 2);
if (nShot == 2 &&
((m_pSecondShot->GetResult() & (CShot::MISS | CShot::FOUL)) != 0))
return 0;
return (nShot == 1) ? m_pFirstShot->GetCount()
: m_pSecondShot->GetCount() - m_pFirstShot->GetCount();
}
Not terrible on its own, but now we have some layered ugliness. It is still prettier than Edward James Olmos.
int CTenthFrame::GetCount(int nShot)
{
ASSERT(nShot >= 1 && nShot <= 3);
switch (nShot)
{
case 1:
return m_pFirstShot->GetCount();
case 2:
if ((m_pSecondShot->GetResult() & (CShot::MISS | CShot::FOUL)) != 0)
return 0;
if ((m_pFirstShot->GetResult() & CShot::STRIKE) != 0)
{
return m_pSecondShot->GetCount();
}
else
{
return (m_pSecondShot->GetCount() - m_pFirstShot->GetCount());
}
case 3:
if ((m_pThirdShot->GetResult() & (CShot::MISS | CShot::FOUL)) != 0)
return 0;
else if (((m_pFirstShot->GetResult() & CShot::STRIKE) != 0)
&& ((m_pSecondShot->GetResult() & CShot::STRIKE) == 0))
return (m_pThirdShot->GetCount()-m_pSecondShot->GetCount());
return m_pThirdShot->GetCount();
}
return -1; // Unreachable without corrupting nShot
}
Now I know I have seen/worked with/written uglier code, but what bothers me about it is that the ugliness is a symptom of earlier architecture decisions I had made and, arguably, forgotten about with code developed later. But on the other hand, I feel reasonably confident about the extensible requirements of this code. I also realize it is doubtful a significant number of people. Plus, the size of this code base will not be terribly large when the application is finished. I think a developer has to know when to compromise elegance for productivity. Well, now that I seem to be going somewhere with this post, namely, appropriately evaluating the need for code quality for a situation, I feel like I am okay posting some of the uglier test code:

Yeah, I got bit in the ass several times because I had no function that attempted to validate a string as a game of bowling before I fed it into the code that mattered. The point is that in realistic software development environments, this could would be refactored if it were to become anything more than throw away test-to-give-the-developer-a-warm-fuzzy code.
Oh, and it is way to big of pain in the the ass to spell check a post when you have this much code. Just assume all typos were either me being tired or having a good enough grasp of the english language to take some liberties with the rules.
