int i, num, year, month, day,d[12];
d[0] = 31;
d[1] = 28;
d[2] = 31;
d[3] = 30;
d[4] = 31;
d[5] = 30;

while (true)
{
num = 0;
scanf("%d",&year);
scanf("%d",&month);
scanf("%d",&day);
if (year % 4 == 0) d[1] = 29;
for (i = 0; i < month - 1; i++) num += d[i];
num += day;
printf("%d",num);
}

printf("Input year,month,day:");
scanf("%d",&year);
scanf("%d",&month);
scanf("%d",&day);
if((year%4==0&&year%100!=0)||year%400==0) date[1]++;
for(int i=0;i result=result+day;
printf("Result is:%d\n",result);
}
