计算日期差的问题 求指点
计算日期差 就是在我输入的1999 4 1和2000 4 1时它输出了365 但是应该是366 求教怎么改……
程序代码：#include
#define isPrime(year) ((year%4==0&&year%100!=0)||(year%400==0))
struct date
{
int year;
int month;
int day;
};
int main(void)
{
int dateDiff(struct date mindate,struct date maxdate);
struct date mindate,maxdate;
int days;
scanf("%i %i %i",&mindate.year,&mindate.month,&mindate.day);
scanf("%i %i %i",&maxdate.year,&maxdate.month,&maxdate.day);
days=dateDiff(mindate,maxdate);
printf("%d\n",days);
return 0;
}
int dateDiff(struct date mindate,struct date maxdate)
{
int days=0,j,flag;
const int primeMonth[][12]={{31,28,31,30,31,30,31,31,30,31,30,31},{31,29,31,30,31,30,31,31,30,31,30,31}};
struct date tmp;
if ((mindate.year>maxdate.year)|| (mindate.year==maxdate.year&&mindate.month>maxdate.month)||(mindate.year==maxdate.year&&mindate.month==maxdate.month&&mindate.day>maxdate.day))
{
tmp=mindate;
mindate=maxdate;
maxdate=tmp;
}
for(j=mindate.year;j<MAXDATE.YEAR;++J)
days+=isPrime(j)?366:365;
flag=isPrime(maxdate.year);
for (j=1;j<MAXDATE.MONTH;J++)
days+=primeMonth[flag][j-1];
flag=isPrime(maxdate.year);
for (j=1;j<MINDATE.MONTH;J++)
days-=primeMonth[flag][j-1];
days=days+maxdate.day-mindate.day;
return days;
}
