3322. 万年历

尝试一下简单小题目——

include

void CaculateWeekDay(int y,int m,int d)
{
if(m==1||m==2){
m+=12;
y–;
}
int iWeek=(d+2m+3(m+1)/5+y+y/4-y/100+y/400)%7;
switch(iWeek){
case 0: printf(“Monday\n”); break;
case 1: printf(“Tuesday\n”); break;
case 2: printf(“Wednesday\n”); break;
case 3: printf(“Thursday\n”); break;
case 4: printf(“Friday\n”); break;
case 5: printf(“Saturday\n”); break;
case 6: printf(“Sunday\n”); break;
}
}
int main()
{
int year=0,month=0,day=0;
scanf(“%d-%d-%d”,&year,&month,&day);
CaculateWeekDay(year,month,day);
return 0;
}
