同理小学生计算题？

还是我没想到什么？

#include <iostream>

using namespace std;

int getTriple(int, int, int, int);

int main ()
{
	int iP;
	int iE;
	int iI;
	int iD;

	int iCount = 0;
	while (cin >> iP >> iE >> iI >> iD)
	{
		iCount ++;
		if (-1 == iP && -1 == iE && -1 == iI && -1 == iD)
		{
			break;
		}

		cout << "Case " << iCount << ": the next triple peak occurs in " << getTriple(iP, iE, iI, iD) << " days." << endl;
	}

	return 0;
}

int getTriple(int iP, int iE, int iI, int iD)
{
	int iPeriodsP = 23;
	int iPeriodsE = 28;
	int iPeriodsI = 33;

	int iCount = iD + 1;
	while (1)
	{
		if ((iCount - iP) % iPeriodsP == 0)
		{
			if ((iCount - iE) % iPeriodsE == 0)
			{
				if ((iCount - iI) % iPeriodsI == 0)
				{
					return iCount - iD;
				}
			}
		}
		iCount ++;
	}
}
