https://www.nowcoder.com/practice/13aeae34f8ed4697960f7cfc80f9f7f6
将闰年和平年的月份用数组表示出来，唯一不同点就是二月份
#include <stdio.h>
int main()
{
int y=0;
int m=0;
int i=0;
int arr1[13]={0,31,29,31,30,31,30,31,31,30,31,30,31};
int arr2[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
while(scanf("%d%d",&y,&m)!=EOF)
{
if(y%4==0&&y%100!=0||y%400==0)
{
printf("%d\n",arr1[m]);
}
else
{
printf("%d\n",arr2[m]);
}
}
return 0;
}
