year2的计算有错

我把程序改为：
#include <iostream.h>
#include <string.h>
#include <stdio.h> 
int main()
{
	char month1[19][9]={"pop", "no","zip","zotz","tzec","xul","yoxkin","mol","chen","yax","zac", 
		"ceh","mac","kankin","muan","pax","koyab","cumhu","uayet" };
	char month2[20][10] ={ "ahau ","imix ", "ik ", "akbal ", "kan ", "chicchan ", "cimi ", "manik ", "lamat ", "muluk ", "ok ", 
		"chuen ","eb ", "ben ", "ix ", "mem ", "cib ", "caban ", "eznab ", "canac "};
	
	int year1,day1,year2,day2,count,day;
	char t,word[10];
	cin>>count;
	cout<<count<<endl;
	while(count--)
	{
		cin>>day1;
		cin>>t;
		cin>>word;
		int i=0;
		for (i=0;strcmp(word,month1[i]);i++);
		int m=i;
		cin>>year1;
		if (m==19)
			day=360+day1;
		else day=m*20+day1;

	    year2=(365*year1+day)/260;

		day+=year1%260*365;
		day++;

		int mon=day%20;
		day2=day%13;
		if (day2==0)
			day2=13;
		cout<<day2<<" "<<month2[mon]<<year2<<endl;
	}
	return 0;
}
就ac了
