APCS程式檢測 -實作題1051029 第4題 棒球遊戲

會使用到二維陣列，如果不清楚可以先來這裡看看

壘包推進
本題的重點在壘包推進的過程
準備 1 個陣列，裡面有 4 個 int

程式碼

//壘包推進
void BaseRun(int* pBasePlayer, int nPlayerNumber, int* pScore, int nNum)
{
	for (int i = 0; i < nNum; i++)
	{
		//模擬跑壘
		for (int j = (BASE_NUM - 1); j >= 1; j--)	//複製前 1 個元素
			pBasePlayer[j] = pBasePlayer[j - 1];

		//設定擊球員上壘
		if(i == 0)	//擊球員
			pBasePlayer[0] = nPlayerNumber;
		else
			pBasePlayer[0] = 0;

		//計算分數
		if (pBasePlayer[BASE_NUM - 1] > 0)	//如果推進過程中本壘有值，分數+1
			*pScore = (*pScore) + 1;
	}
}
