解题思路以及注意事项：
今天给大家分享的这题不难，但很搞笑哈。
好久没写过怎么恶心的代码了，今天给大家开开眼哈。
实例代码：
#include"stdio.h"
struct year
{
int years;
int month;
int days;
};
int main()
{
int t=0;
struct year yeari;
scanf("%d %d %d",&yeari.years,&yeari.month,&yeari.days);
if(((yeari.years%4)==0)&&(yeari.years%100)!=0||((yeari.years%400)==0))
{
if(yeari.month==1)
{
t=yeari.days;
}
if(yeari.month==2)
{
t=yeari.days+31;
}
if(yeari.month==3)
{
t=yeari.days+31+29;
}
if(yeari.month==4)
{
t=yeari.days+31+29+31;
}
if(yeari.month==5)
{
t=yeari.days+31+29+31+30;
}
if(yeari.month==6)
{
t=yeari.days+31+29+31+30+31;
}
if(yeari.month==7)
{
t=yeari.days+31+29+31+30+31+30;
}
if(yeari.month==8)
{
t=yeari.days+31+29+31+30+31+30+31;
}
if(yeari.month==9)
{
t=yeari.days+31+29+31+30+31+30+31+31;
}
if(yeari.month==10)
{
t=yeari.days+31+29+31+30+31+30+31+31+30;
}
if(yeari.month==11)
{
t=yeari.days+31+29+31+30+31+30+31+31+30+31;
}
if(yeari.month==12)
{
t=yeari.days+31+29+31+30+31+30+31+31+30+31+30;
}
}
else
{
if(yeari.month==1)
{
t=yeari.days;
}
if(yeari.month==2)
{

{

}
if(yeari.month==6)
{

}
if(yeari.month==7)
{
t=yeari.days+31+28+31+30+31+30;
}
if(yeari.month==8)
{
t=yeari.days+31+28+31+30+31+30+31;
}
if(yeari.month==9)
{
t=yeari.days+31+28+31+30+31+30+31+31;
}
if(yeari.month==10)
{
t=yeari.days+31+28+31+30+31+30+31+31+30;

}
if(yeari.month==12)
{
t=yeari.days+31+28+31+30+31+30+31+31+30+31+30;
}
}
printf("%d",t);
return 0;
}相信大家都懂了，可以在下方评论区留言，批判批判哈
