刷題記錄，新手勿怪

解题思路:

注意事项:

参考代码:

#include<stdio.h>

//定義結構體DATE

struct DATE

{

int year;

int month;

int day;

};

int main(void)

{

struct DATE data;

int y=data.year;

int m=data.month;

int d=data.day;

int M_D_D[12]={31,0,31,30,31,30,31,31,30,31,30,31};

int i;

int sum=0;

scanf("%d %d %d",&y,&m,&d);

//閏年判斷，給二月天數賦值

if(y%4==0&&y%100!=0||y%400==0){

M_D_D[1]=29;

} else {

M_D_D[1]=28;

}

//遍歷數組累加天數

for(i=0;i<m-1;i++){

sum+=M_D_D[i];

}

sum+=d;

printf("%d",sum);

}
